Question

a) 4(x − 3) = 2x-3
b) 2( 2x - 4) = 16
c) 6x +8-5 = 3x +9​

Answer 1

Respuesta:

$a)4(x - 3) = 2x - 3 \\ 4x - 12 = 2x - 3 \\ 4x - 2x = - 3 + 12 \\ 2x = 9 \\ x = \frac{9}{2}$

$b)2(2x - 4) = 16 \\ 4x - 8 = 16 \\ 4x = 16 + 8 \\ 4x = 24 \\ x = 6$

$c)6x + 8 - 5 = 3x + 9 \\ 6x + 3 = 3x + 9 \\ 6x - 3x = 9 - 3 \\ 3x = 6 \\ x = 2$
