Question

A.5-3(×+6)=7(x-1)
B.2(×+1)-5x=3-2(×-1)

Answer 1

Hola!!

$\boxed {\displaystyle \mathbb {PROCEDIMIENTO:}}$

$\bf{5-3\left(x+6\right)=7\left(x-1\right)}\\-3x-13=7x-7\\-3x=7x+6\\-10x=6\\x=-\dfrac{6}{10}\\\\x=-\dfrac{3}{5}$

$\bf{2\left(x+1\right)-5x=3-2\left(x-1\right)\\}\\-3x+2=-2x+5\\-3x=-2x+3\\-x=3\\x=-3$
