Solve: 7(3x+5) = 8x - (1-4x)?


Let's rewrite as

7(3x+5) = 8x -1(1-4x)
Let's distribute
21x + 35 = 8x -1 + 4x
collect like terms
21x + 35 = 12x -1
Put all the x's on one side by subtracting 12x from both sides
21x -12x + 35 = 12x -1 -12x
simplify
9x + 35 = -1
get all the constants on the right side
9x + 35 - 35 = -1 - 35
9x = -36
divide both sides by 9 to get x by itself
9x /9 = -36/9
x = -4

check in original equation

7(3(-4)+5) = 8(-4) -(1-4(-4))
7(-12+5) = -32 - (1+16)
7 (-7) = -32 - (17)
-49 = -32-17
-49 = -49

Demonstrate how to multiply two binomials


Try to seek these: By using the suggested format:
Suggested su
  1. Adding and Subtracting Binomials
    • 1

      Arrange each term in each binomial in order of degree from greatest to least. The degree of a binomial is the exponent attached to the term. For example, 4x^2 is a second degree term.

    • 2

      Multiply each term in the binomial that is being subtracted by -1 to turn it into an addition problem. For example, the problem (8x^2 + 8) - (x^2 - 2) becomes (8x^2 + 8) + (-x^2 + 2).

    • 3

      Combine like terms. In the example problem, the x^2 terms are combined and the constant terms are combined, yielding (8x^2 + 8) + (-x^2 + 2) = 7x^2 + 10.

    Multiplying Binomials
    • 4

      Understand the F.O.I.L. method. F.O.I.L. is an acronym standing for first, outside, inside and last. It means that you multiply the first number of the first binomial by the first number of the second, then the numbers on the outside (the first term of the first binomial by the second term of the second binomial) and so on. This ensures that both numbers in the first binomial are multiplied by both numbers in the second.

    • 5

      Use the F.O.I.L. method to multiply the two binomials together. For example, (3x + 4)(3x - 4) = 9x^2 +12x - 12x - 16. Notice that -12x is the product of the outside terms and -16 is the product of the last terms, 4 and -4.

    • 6

      Simplify. There will almost always be like terms to combine. In the example, 12x and -12x cancel out, yielding the answer 9x^2 - 16.

    Dividing Binomials
    • 7

      Use the distributive property to divide both terms in the binomial by the monomial divisor. For example, (18x^3 + 9x^2) / 3x = (18x^3 / 3x) + (9x^2 / 3x).

    • 8

      Understand how to divide by a term. If you are dividing a higher order term by a lower order term, you subtract the exponent. For example, y^3/y = y^2. The number part of each term is handled like any other division problem. For example, 20z / 4 = 5z.

    • 9

      Divide each term in the binomial by the divisor; (18x^3 / 3x) + (9x^2 / 3x) = 6x^2 + 3x.

Slope and y intercept


Simplify and put it into slope-intercept form:
y=9x-15

From the above the slope is readily seen to be 9 and the y-intercept is -15.
