Question

Solve the following equation. 3(2x - 4) = 4(x + 1) x=?

Answer 1

Answer:

$x=8$

Step-by-step explanation:

$3\left(2x-4\right)=4\left(x+1\right)$

Expand:

$3\times 2x-3\times 4=4x+4\times 1$

$6x-12=4x+4$

Add 12 to both sides:

$6x-12+12=4x+4+12$

$6x=4x+16$

Subtract 4x from both sides:

$6x-4x=4x+16-4x$

$2x=16$

Divide both sides by 2:

$\frac{2x}{2}=\frac{16}{2}$

$x=8$
