Question

solve the equation 3x +5=0.5-7​

Answer 1

3x+5=0.5x-7

We move all terms to the left:

3x+5-(0.5x-7)=0

We get rid of parentheses

3x-0.5x+7+5=0

We add all the numbers together, and all the variables

2.5x+12=0

We move all terms containing x to the left, all other terms to the right

2.5x=-12

x=-12/2.5

x=-4+1/1.25
