Question

Resolva as equacões

a) 18x - 43 = 65

b) 23x - 16 = 14 - 17x​

Answer 1

Explicação passo-a-passo:

a) 18x - 43 = 65

18x = 65 + 43

18x = 108

x = 108/18

x = 6

b) 23x - 16 = 14 - 17x

23x + 17x = 14 + 16

40x = 30

x = 30/40

x = 0,75

espero ter ajudado!

Answer 2

BOM DIA^_^

• calcule os termos semelhantes.

$\tt \: a)18x -43=65 \\ \tt \: 18x = 65 + 43 \\ \tt18x = 108 \\ \tt \: x = \frac{108}{18} = \red{6}$

______________________________

$\tt \: b)23x -16=14 -17x \\ \tt 23x + 17x = 14 + 16 \\ \tt \: 40x = 30 \\ \tt \: x = \frac{30}{40 } = \red{0.75}$

BONS ESTUDOS!
