Question

7x + 18 = 16 + 4x qual a conta e resultado?

Answer 1

Resposta:

x = - 2/3

Explicação passo-a-passo:

7x + 18 = 16 + 4x

7x - 4x = 16 - 18

3x = - 2

x = - 2/3

Answer 2

Resposta:

$7x + 18 = 16 + 4x \\\\7x+18-18=16+4x-18\\\\7x=4x-2\\\\7x-4x=4x-2-4x\\\\3x=-2\\\\\frac{3x}{3}=\frac{-2}{3}\\\\x=-\frac{2}{3}$
