Question

1)8x-30=3x+10

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

Answer 1

1)8x-30=3x+10
8x - 3x = 10 + 30
5x = 40
x = 40/5
x = 8

2)3(2x-1)+2(2+3x)=3
6x - 3 + 4 + 6x = 3
6x + 6x = 3 + 3 - 4
12x = 6 - 4
12x = 2
x = 2/12      simplifica 2 e 12 por 2
x = 1/6

Answer 2

1) 8x-3x=10+30
5x=40
x=40/5

2) 3(2x-1)+2(2+3x)=3
6x-3+4+6x=3
6x+6x=3+3-4
12x=2
x=12/2
x=6
