QUESTÃO 01

Resolva as seguintes equações:

x + 10 = 32

3x + 8 = 32

4x + 13 = 28

10x - 20 + 4x = 8

Answer 1

1.

$x + 10 = 32\\x = 32 - 10\\\boldsymbol{x = 22}$

2.

$3x + 8 = 32\\3x = 32 - 8\\3x = 24\\x = \frac{24}{3}\\\boldsymbol{x = 8}$

3.

$4x + 13 = 28\\4x = 28 - 13\\4x = 15\\\boldsymbol{x = \frac{15}{4}}$

4.

$10x - 20 + 4x = 8\\10x + 4x = 8 + 20\\14x = 28\\x = \frac{28}{14}\\\boldsymbol{x = 2}$
