Question

360x=360×(x-3)+10×(x-3)​

Answer 1

Resposta:

360x=360×(x-3)+10×(x-3)

360x=360x-1080+10×(x-3)

360x=360x-1080+10x-30

0=-1080+10x-30

0=-1110+10x

-10x=-1110

-10x: (-10)  = -1110:(-10)

​x=111

Answer 2

Explicação passo-a-passo:

$360x = 360 \times (x - 3) + 10 \times (x - 3) \\ 360x = 360x - 1080 + 10x - 30 \\ 0 = - 1080 + 10x - 30 \\ 0 = - 1110 + 10x \\ - 10x = - 1110 \\ x = - 1110 \div (- 10) \\ x = 111$
