Question

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

Answer 1

`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

`( - 6)/( - 6)x = (12)/( - 6) \\`

`x = - 2`

It is must be in the box buddy.

And we're done...♥️♥️♥️♥️♥️
