3(x-5)+2x=x-12

Question

3(x-5)+2x=x-12

Answer 1

3(x-5) = 3x-15

 

so 3x-15+2x = x-12

 

we can combine 3x+2x to get 5x

 

so 5x-15 = x-12

 

now 5x-15-x = x-x-12  => 4x-15 = -12

 

now add 15 to both sides

 

4x-15+15 = -12+15 =>  4x = 3  => x=3/4     and that's the final answer

 

 

 

Answer 2

3(x - 5) + 2x = x - 12

 

 

First, we distribute the terms to get rid of parentheses.

 

3x - 15 + 2x = x - 12

 

 

Combine like terms on each side of equation where necessary.

 

5x - 15 = x - 12

 

 

Subtract x on both sides of equation.

 

4x - 15 = -12

 

 

Add 15 on both sides of equation.

 

4x = 3

 

 

Divide both sides of equation by 4.

 

x = 3/4
