Question

Equação 6×-4(×-5)-(5-3×)=0

Answer 1

$\LARGE\tt{}6x - 4(x - 5) - (5 - 3x) = 0 \\ \LARGE\tt{}6x - 4x + 20 - (5 - 3x) = 0 \\ \LARGE\tt{}6x - 4x + 20 - 5 + 3x = 0 \\ \LARGE\tt{}5x + 20 - 5 = 0 \\ \LARGE\tt{}5x + 15 = 0 \\ \LARGE\tt{}5x = - 15 \\ \\ \LARGE\tt{}x = \frac{ - 15}{5} \\ \\ \LARGE\tt{}x = - 3 \\ \\ \LARGE\tt{}s: \{ - 3 \}$

Answer 2

Vamos lá.

6x - 4*(x - 5) - (5 - 3x) = 0

6x - 4x + 20 - 5 + 3x = 0

5x + 15 = 0

5x = -15

x = -3
