-42x^2 - 36/x^2 + 18x + 47/48x^2 - 4

I am confident that this is the simplified form.

-26 x^2-2449/(48 x^2)+18 x-4 or -(1248 x^4-864 x^3+192 x^2+2449)/(48 x^2)

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

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

4X+3-3=3X-4-3=3X-7

4X=3X-7

4X-3X=3X-3X-7

X=-7

The answer is X=-7

4X=3X-7

4X-3X=3X-3X-7

X=-7

The answer is X=-7

-3x + 3 + 4x +2

2 + 3 = 5, so we simplify that bit:

-3x + 4x + 5

Then we'll look at the 'x' bits. We're multiplying x by -3 and we're also multiplying by 4. We don't need all that, so to get the total amount of times we need to multiply x, we add -3 and 4, which gives us 1x...or just x.

So:

Answer: x + 5

2 + 3 = 5, so we simplify that bit:

-3x + 4x + 5

Then we'll look at the 'x' bits. We're multiplying x by -3 and we're also multiplying by 4. We don't need all that, so to get the total amount of times we need to multiply x, we add -3 and 4, which gives us 1x...or just x.

So:

Answer: x + 5

7x-3 + 3x = -53

7x + 3x - 3 = -53

10x - 3 = -53

10x = -53 + 3

10x = -50

x = -5

Therefore 4x + 9 is equal to 4 times (-5) plus 9

-20 + 9 equals -11

7x + 3x - 3 = -53

10x - 3 = -53

10x = -53 + 3

10x = -50

x = -5

Therefore 4x + 9 is equal to 4 times (-5) plus 9

-20 + 9 equals -11

Hello,

This calculator cannot handle symbolic algebra.

Use the rules to simplify the expressions: Get rid of the parentheses using distributivity od multiplication with respect to addition; group similar terms (terms with x, terms without x).

Hope it helps.
