Question

A) 2(x+1)=-7(x+3)+3(3x-5)-5
B)4(x+5)-3(x-3)=2(x+15)
C)5(x+2)-4(x-2)=3(x+8)
D)3(2x-7)-5(3x+1)+4x=8-2(5x-3)

Answer 1

a) 2x+2=-7x-21+9x-15-5
2x+7x-9x=-2-21-20
0=-43 (f)

b)
4x+20-3x+9=2x+30
4x-3x-2x=30-9-20
-x=1
x=-1
c)
5x+10-4x+8=3x+24
5x-4x-3x=24-8-10
-2x=6
x=-3
d)
6x-21-15x-5+4x=8-10x+6
6x-15x+4x+10x=8+6+5+21
5x=40
x=8
