Question

-5 = 7 – 3x


. 14 = -2 + 8x/3


x/3 + 2=5


2/(x-1)+3=20/(x-1)+2

2x/4+3x=30-x

Answer 1

-5=7-3x
3x=7+5
x= 12/3
x= 4

14= -2+8x/3
8x/3=14+2
8x= 16*3
x= 48/8
x= 6

x/3 + 2=5
x/3=5-2
x= 3/3
x=1

2/x-1  +3=20/x-1  +2
20/x-1 -2/x-1 = 3-2
18/x-1 = 1
18= 1(x-1)
18+1= x
x=19

2x/4 +3x=30-x
2x/4=30-x-3x
2x/4=30-4x
2x=(30-4x)4
2x=120-16x
2x+16x=120
18x=120
x=120/18
x= 6.666

espero que te sea de ayuda
