Question

Qual o resultado da equação 3x – 10 + 13 = – 2x + 28? *

Answer 1

Resposta:

x=5

Explicação passo-a-passo:

$3x-10+13=-2x+28\\\\3x+3=-2x+28\\\\3x+3-3=-2x+28-3\\\\3x=-2x+25\\\\3x+2x=-2x+25+2x\\\\\\5x=25\\\\\\\frac{5x}{5}=\frac{25}{5}\\\\x=5$

Answer 2

Olá!

$\\ { \large \displaystyle \sf {3x - 10 + 13 = - 2x + 28}}$

${ \large \displaystyle \sf {3x + 3 = - 2x + 28}}$

${ \large \displaystyle \sf {3x + 2x = 28 - 3}}$

${ \large \displaystyle \sf {5x = 25}}$

${ \large \displaystyle \sf {x = \frac{25}{5} }}$

$\boxed{ \boxed{ \pink{{ \large \displaystyle \sf {x = 5}}}}}$

O valor de X = 5
