Question

√16-2x=14 como montar a conta

Answer 1

Resposta:

se for √16-2x=14

4-2x=14

2x=4-14

2x=-10

x=-5

se for √(16-2x)=14

√(16-2x)²=14²

16-2x =196

2x=16-196

2x=-180

x=-90

Answer 2

Resposta:

x = -90

Explicação passo a passo:

$\sqrt{16-2x}=14\\\\(\sqrt{16-2x})^2=14^2\\\\16-2x=196\\\\-2x=196 - 16\\\\-2x=180 \\\\2x=-180\\\\x=-\frac{180}{2}\\\\x= -90$
