Pfvr me ajudem ( pra hoje)

Answer 1

A) 6x-3x=-5-10
3x= -15
x=15/3 = -5

B)18-8x=200+100
10x=300
x=300/10 = 30

C)10x-9x=-37+137
x=100

D)7x-3x=7+21
4x=28
x=28/4 = 7

Answer 2

A)6x+10=3x-5
6x-3x=-10-5
3x=-15
x=-15/3
x=-5

B)18x-100=8x+200
18x-8x=200+100
10x=300
x=300/10
x=30

C)10x-137=9x-37
10x-9x=137-37
x=100

D)7x-21+=3x+7
7x-3x=21+7
4x=28
x=28/4
x=7

Bons estudos!!
