Question

Resolver: a. 6(x – 2)– 3(x – 1) = 4x + 3(x – 2) ; b. 6x – 4 + 3x = 7x + 30 +x – 8

Answer 1

Respuesta:

a.

$6(x - 2) - 3(x - 1) = 4x + 3(x - 2) \\ 6x - 12 - 3x + 3 = 4x + 3x - 6 \\ - 12 + 3 + 6 = 4x + 3x + 3x \\ - 3 = 10x \\ x = \frac{ - 3}{10}$

b.

$– 4 + 3x = 7x + 30 +x – 8 \\ - 4 - 30 + 8 = 7x + x - 3x \\ - 26 = 5x \\ x = \frac{ - 26}{5}$
