Question

resolva as equação 3x+4-x=8+5x+3​

Answer 1

Resposta:

\begin{gathered}a)5x - 4 = 3x - 8 \\ 5x - 3x = - 8 + 4 \\ 2x = - 4 \\x = - 2 \\ \\ b) \frac{x}{5} + 8 = \frac{4}{3} - 2x \\ \frac{3x + 120}{15} = \frac{20 - 30x}{15} \\ 3x + 120 = 20 - 30x \\ 33x = - 100 \\ x = \frac{ - 100}{33} \\x = - 3.03\end{gathered}a)5x−4=3x−85x−3x=−8+42x=−4x=−2b)5x+8=34−2x153x+120=1520−30x3x+120=20−30x33x=−100x=33−100x=−3.03
