A) 2 (x-1) +3(x+1) =4 (x+2)
B) 5 (2x +7) -1 = 4 ( x - 5)+9
C) 2(x+1) +5 (x-1)=7
D) 2 (2x+3)+5(x+1)= 8 - 3(x-1)

Answer 1

A) 2x-2+3x+3=4x+8

2x+3x-4x=8+2

x=10

B) 10x+35-1=4x-20+9

10x-4x=9-20-35+1

6x= 53

x=53/6

C) 2x+2+5x-5=7

2x+5x=7-2+5

7x=10

x=10/7

D)4x+6+5x+5=8-3x+3

4x+5x+3x=8+3-6-5

12x=11-11

12x=0

x=0/12

x=0
