Question

How do i solve -3x--3+8x-24=6x+7-5x

Answer 1

Answer:

$x=7$

Step-by-step explanation:

$-3x--3+8x-24=6x+7-5x$

Two negative signs equate to a positive sign, so we can write $--3$ as just $3$:

$-3x+3+8x-24=6x+7-5x$

Add up similar terms:

$5x-21=x+7$

Add 21 to both sides:

$5x-21+21=x+7+21$

$5x=x+28$

Subtract x from both sides:

$5x-x=x+28-x$

$4x=28$

Divide both sides by 4:

$\frac{4x}{x} =\frac{28}{4}$

$x=7$
