$\frac{x}{3} +5 = \frac{x-1}{2} \\\\\frac{x}{3} +4 = \frac{3x}{2}$

Answer 1

Resposta:

I ) x = 33  II ) x = 24 / 7

Explicação passo-a-passo:

$A) \\\frac{(x + 15)}{3} =\frac{(x - 1)}{2} (emcruz) \\2(x + 15) = 3(x - 1) = 2x + 30 = 3x - 3\\30 + 3 = 3x - 2x\\x = 33\\\\B)\\\frac{x + 12}{3} = \frac{3x}{2} = 2(x + 12) = 3.3x\\  2x + 24 = 9x\\24 = 9x - 2x\\\\7x = 24 \\\\x = 24 / 7$

Answer 2

resolução!

x/3 + 5 = x - 1/2 ____ MMC = 6

2x + 30 = 3x - 3

2x - 3x = - 3 - 30

- X = - 33 * (-1)

X = 33

___________________________________________________________

x/3 + 4 = 3x/2 ______ MMC = 6

2x + 24 = 9x

2x - 9x = - 24

- 7x = - 24 * (-1)

X = 24/7
