4x+7=2(x-3)

4x+7=2x-6

4x-2x=-7-6

2x = -13

2x/2 = -13/2

x = -6.5

Let us backtrack so as to better jump.

An algebraic expression may contain one or several**algebraic terms**, separated by a plus sign or a or a minus and a sign.

Each algebraic term is the product of a constant coefficient and a power of some variable, or the powers of several variables.

Example of an algebraic term 3(x^2)(y^6)....

**If the exponents of the various powers are positive integers, the term is called a monomial. **In short no square roots, or fractionary powers of the variables appear in monomials. Thus 2/x, 3SQRT(x), or 1/x^5 are not monomials.

Finally, a polynomial is an**algebraic expression** made up of one or more monomials.

Example P(X)=(1/3)X^7-(SQRT(5)*X^4+ 16X-25 is a polynomial of degree 7 in the indeterminate/variable X

Q(X,Y)= 3(X^3)*Y^2 + 4X-5Y+10 is a polynomial of degree 5 in the variables X and Y.

If your question is the inverse of 3x / (4x - 1) then

(4x - 1) / 3x

If you meant (3x / 4x) - 1 then

- 4

(4x - 1) / 3x

If you meant (3x / 4x) - 1 then

- 4

Start by combining like terms on each side of the equation.

Remember, when working with variables the real numbers always come last in the equation(i.e. 5+x-7=x+5-7)

Once you have this completed move all variables to one side and all whole numbers to the other side. Solve from there.

try to collect the like terms:-20=-10x

divide both sides the coefficient of X which -10

X=-20/-10

X=2

divide both sides the coefficient of X which -10

X=-20/-10

X=2

You just need to divide the 56 by 7 in order to get the right base, then multiply that result by 4 and then 3 in order to get the answers. So...

56/7 is 8. 8*4 is 32, and 8*3 is 24.

32Kg and 24Kg

You can do this with algebra as well, equation is 4x + 3x = 56.
