Question

3(x+2)-1=2(x+3)-7
3(x+1)+2=5+2(x-1)
5(2x+7)-1=4(x-5)+9
2(x+1)+5(x-1)=7
2(x-1)+3(x+1)=4(4x+2)

Answer 1

3(x+2)-1=2(x+3)-7
3x+6-1=2x+6-7
3x-2x=6-7-6+1
x=-6

3(x+1)+2=5+2(x-1)
3x+3+2=5+2x-2
3x-2x=5-2-3-2
x=-2

5(2x+7)-1=4(x-5)+9
10x+35-1=4x-20+9
10x-4x=-20+9+1-35
6x=-45
x=-45/6 = -15/2

2(x+1)+5(x-1)=7
2x+2+5x-5=7
2x+5x=7+5-2
7x=10
x=10/7

2(x-1)+3(x+1)=4(4x+2)
2x-2+3x+3=16x+8
2x+3x-16x=8-3+2
-11x=7(-1)
11x=-7
x=-7/11

Answer 2

3(x+2)-1=2(x+3)-7

3 x +6-1=2 x+6-7

+18-1 + 12 - 7

+17 + 12 - 7

+29 - 7

+22

3(x+1)+2=5+2(x-1)

3 x+3+2=5+2 x-2

+9+ 2 = 5 + -4

+11 - 1 +

+12

5(2 x+7)-1=4(x-5)+9

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

+350 - 1 = -80 +9

+349  -89

+260

2(x+1)+5(x-1)=7

2 x +2+5 x-5=7

+4+ 5 x - 5 = 7

+9 x - 5 = 7

-45 - 7

-38

2(x-1)+3(x+1)=4(4 x+2)

2 x - 1 + 3 x + 1 = 4(4 x  2)

-1 + 3 x + 1 = 4 ( 4 x 2)

-4 x + 1 =( 4 x 2)

-4 = ( 4 x 2)

4 - 8
