Question

4m+4=20

5m-6=24

w+3=7

k+6=1

resolva as equaçoes!​

Answer 1

$a) \: 4m + 4 = 20 \\ 4m = 20 - 4 \\ 4m = 16 \\ m = \frac{16}{4} \\ \boxed{ \bf{m = 4} }$

$b) \: 5m - 6 = 24 \\ 5m = 24 + 6 \\ 5m = 30 \\ m = \frac{30}{5} \\ \boxed{ \bf{m = 6} }$

$c) \: w + 3 = 7 \\ w = 7 - 3 \\ \boxed{ \bf{w = 4} }$

$d) \: k + 6 = 1 \\ k = 1 - 6 \\ \boxed{ \bf{k = - 5} }$

Espero ter ajudado! :)

Answer 2

4m+4=30
4m=20-4
4m=16
m=4


5m-6=24
5m=24-6
5m=18
m=3,6

W+3=7
W=7-3
W=4

K+6=1
K=1-6
K=-5
