por favor me ajudem,eu ajudo vcs tbm

Answer 1

a) 7(x-5)=3(x+1)
7x-35=3x+3
7x-3x=3+35
4x=38
x=38/4 (÷2)
x=19/2
b) 3(x-2)=4(-x+3)
3x-6=-4x+12
3x+4x=12+6
7x=18
x=18/7
c) 2(x+1)-(x-1)=0
2x+2-x+1=0
2x-x=-1-2
x=-3
d) 5(x+1)-3(x+2)=0
5x+5-3x-6=0
5x-3x=6-5
2x=1
x=1/2
e) 13+4(2x-1)=5(x+2)
13+8x-4=5x+10
8x-5x=10+4-13
3x=14-13
3x=1
x=1/3
f) 4(x+5)+3(x+5)=21
4x+20+3x+15=21
4x+3x=21-15-20
7x=21-35
7x=-14
x=-14/7
x=-2
g) 2(x+5)-3(5-x)=10
2x+10-15+3x=10
2x+3x=10+15-10
5x=25-10
5x=15
x=15/5
x=3
h) 8(x-1)=8-4(2x-3)
8x-8=8-8x+12
8x+8x=8+12+8
16x=28
x=28/16
x=1,75
