Question

How do you work out this math problem?? 2+2x-5=5(x+3)

Answer 1

1) Simplify the problem

This involves combining variables

2-5=-3

Now that is -3+2x= 5x+15

2) Find the hidden variable.

Now that the problem is in order you can find the hidden variable of x.

So think what number in place of x makes this equation true?

There are may ways you can solve for x, including the substitution method.

Answer 2

The first step i'd take is distributing the right side, by multiplying everything in the parentheses by 5 , so ; 2+2x-5=5x+15

then you could gather similar or like terms on one side, by moving all the x terms to the right, and all the regular terms to the left. to do this, you do the same thing on both sides of the equation

 2 +2x -5   = 5x +15      
    -2x -15 = -2x -15

2-5-15 = 3x
