To make the expression 4x-2 + (2x + 4) equivalent to 2(6x + 7), what must be the value in the box?

podryga [215]

$4x - 2 + (2x + 4) = 2(6x + 7) \\$

$4x - 2 + 2x + 4 = 12x + 14$

Simplification

$6x + 2 = 12x + 14$

Subtract sides 2

$6x + 2 - 2 = 12x + 14 - 2$

Simplification

$6x = 12x + 12$

Subtract sides -12x

$6x - 12x = 12x - 12x + 12$

Simplification

$- 6x = 12$

Divided sides by -6

$\frac{ - 6}{ - 6}x = \frac{12}{ - 6} \\$

$x = - 2$

It is must be in the box buddy.

And we're done...♥️♥️♥️♥️♥️
