Question

Determine o valor de x e y nas alternativas abaixo, sabendo que r//s

Answer 1

Resposta:

A) Resolvendo X

$5x - 7 = 3x + 17 \\ 5x - 3x = 17 + 7 \\ 2 x = 24 \\ x = \frac{24}{2} \\ x = 12$

Resolvendo Y

$5x - 7 + y = 180\\ 5.12 - 7 + y = 180 \\ 60 - 7 + y = 180 \\ 53 + y = 180 \\ y = 180 - 53 \\ y = 127$

B)Resolvendo X

$3x + 12 + 2x + 8 = 180 \\ 3x + 2x = 180 - 12 - 8 \\ 5x = 160 \\ x = \frac{160}{5} \\ x = 32$

Resolvendo Y

$3x + 12 = y \\ 3.32 + 12 = y \\ 96 + 12 = y \\ y = 108$
