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
where y2=1 , y1=6 , x2=4 , x1=8.
