Question

1) resolva as operações:

a) 5m - 18 = 7m - 26

b) 13x + 35 = 8x + 60

Answer 1

Resposta:

a) m = 4

5m - 18 = 7m - 26

5m-18-7m=-26

5m-7m=-26+18

-2m=-26+18

-2m=-8

8÷2

$\rightarrow\boxed{\boxed{\sf{m = 4}}}\checkmark$

b) x = 5

13x + 35 = 8x + 60

13x+35-8x=60

13x-8x=60-35

5x=60-35

5x=25

25÷5

$\rightarrow\boxed{\boxed{\sf{x = 5}}}\checkmark$
