Question

Resolução:

$1 + \frac{5z - 36}{4} + \frac{2 - z}{2} = 2 + \frac{z - 12}{2}$

Answer 1

$1+ \frac{5z-36}{4} + \frac{2-z}{2} =2+ \frac{z-12}{2} \\ \\ mmc(2,4)=4 \\ \\ 4+1(5z-36)+2(2-z)=8+2(z-12) \\ 4+5z-36+4-2z=8+2z-24 \\ 8-36+3z=-16+2z \\ -28+3z=-16+2z \\ 3z-2z=-16+28 \\ z=12 \\ \\ S=\{12\}$
