Answer 1

Resposta:

2

Explicação passo-a-passo:

$5(x - 8) + x = 4x - 50 \\ \\ 5x - 40 + x = 4x - 50 \\ \\ 5x + x - 4x = - 50 + 40 \\ \\ 6x - 4x = - 10 \\ \\ 2x = - 10 \\ \\ 2x = -10 \\ \\ x = \frac{-10}{2} \\ \\ \orange x \orange = \orange-5$

Answer 2

$\large \sf 5(x – 8) + x = 4x – 50 \\ \\ \large \sf 5x - 40 + x = 4x - 50 \\ \\ \large \sf5x + x - 4x = - 50 + 40 \\ \\ \large \sf2x = - 10 \\ \\ \large \sf10 \div 2 \\ \\ \large \sf \boxed{ \boxed {\sf x =- 5 }}$
