Question

Solve 7+3x-12x=3x+1 What does X equal?? plz help!

Answer 1

Answer:

x = 0.5 or $\frac{1}{2}$

Step-by-step explanation:

7+3x-12x=3x+1

  -3x      =-3x     cross out 3x

$7-12x=1$  subtract 7 on both sides

-7          =-7

$-12x=-6$ divide -12 into both sides

$\frac{-12x}{-12} = \frac{-6}{-12}$  cross out -12 and divide -6/-12 = 0.5

To check

7+3(0.5)=8.5 - 12(0.5)=2.5

3(0.5)=1.5+1= 2.5
