X= 14.375
I don't know what the question is asking for the fractions part down below but to get to x:
First you Distribute.
1.5•4x=6x
1.5•-1=1.5
Combined it's 3x-1.5.
The second part:
Distribute again:
-1•x= -x
-1•2= -2
Combined it's 56-x
All Together it's 3x-1.5=56-x
Solve that and you get x=14.375
