Question

a) -4x = 8

b)2x - 1 = x - 10

c)3 - 2x - 3 = x - 18

d)5x - 10 = 4 + 2x - 1

Answer 1

Resposta:

Explicação passo a passo:

a) -4x = 8

x=8+4

x=12

b)2x - 1 = x - 10

2x-x=-10+1

x=-9

c)3 - 2x - 3 = x - 18

-2x-x=-18+3-3

-3x=-18 (*-10

3x=18

x=18/3

x=6

d)5x - 10 = 4 + 2x - 1

5x-2x=4-1+10

3x=13

x=13/3
