Question

6(x+3)-7(x+5)=4(x+1)-2(x+6)+12
5(2x-7)-3(3x-8)=9x-2(3x-5)+13
3(4x-11)+5(7-2x)=16-2(3x-10)
7(5x-8)+6(5-3x)=28-8(3x-4x)
17(2-3x)-5(x+12)=8(1-7x)+4+19x

Answer 1

5(2x-7)-3(3x-8)=9x-2(3x-5)+13
10x-35-9x+24=9x-6x-10+13
x-11=3x+3
x-3x=3+11
-2x=14
x=-7


6(x+3)-7(x+5)=4(x+1)-2(x+6)+12
6x+18-7x-35=4x+4-2x-12+12
-x-17=2x+4
-x-2x=4+17
-3x=21
x=-7

3(4x-11)+5(7-2x)=16-2(3x-10)
12x-33+35-10x=16-6x+20
2x+2=36-2
8x=34
x=17/4


7(5x-8)+6(5-3x)=28-8(3x-4x)
35x-56+30-18x=28-8*(-x)
17x-26=28+8x
17x-8x=28+26
9x=54
x=6


17(2-3x)-5(x+12)=8(1-7x)+4+19x
34-51x-5x-60=8-56x+4+19x
-26-56x=12-37x
-56x+37x=12+36
-19x=38
x=-2
