Question

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

Answer 1

x = 0.5 or
`(1)/(2)`

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

`(-12x)/(-12) = (-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
