Oie, tudo bom?
a)
[tex]3 + z = 0 \\ \boxed{z = - 3}[/tex]
b)
[tex]23a + 2 = 2 \\ 23a = 2 - 2 \\ 23a = 0 \\ a = \frac{0}{23} \\ \boxed{a = 0}[/tex]
c)
[tex]12 - 7 + 4x = 25 \\5 + 4x = 25 \\ 4x = 25 - 5 \\ 4x = 20 \\ x = \frac{20}{4} \\ \boxed{x = 5}[/tex]
d)
[tex]5x - 3x = 30 \\ 2x = 30 \\ x = \frac{30}{2} \\ \boxed{x = 15}[/tex]
e)
[tex]4y + 10 = 45 - 3y \\ 4y + 3y = 45 - 10 \\ 7y = 35 \\ y = \frac{35}{7} \\ \boxed{y = 5}[/tex]
