Question

quanto e 3 – 2(x + 3) = x – 18

b) 50 + (3x − 4) = 2(3x – 4) + 26

Answer 1

Resposta:

3 – 2(x + 3) = x – 18

3-2x+6=x-18

-2x-x=-18+3-6

-3x=-15

x=-15÷(-3)

x=+5

b) 50 + (3x − 4) = 2(3x – 4) + 26

50+3x-4=6x-8+26

3x-6x=-8+26-50-4

-3x=+14-50

-3x=-36

x=-36÷(-3)

x=12

espero que isso ajude vc
