x=2

Answer 2

Answer:

$x=2$

Step-by-step explanation:

We have been given an equation $4x+8=16$. we are asked to find the value of x that makes our given equation true.

Let us solve our given equation for x using opposite operations.

Subtract 8 from both sides:

$4x+8-8=16-8$

$4x=8$

Divide both sides by 4:

$\frac{4x}{4}=\frac{8}{4}$

$x=2$

Therefore, $x=2$ is the solution for our given equation.

Let us verify our answer:

$4x+8=16$

$4(2)+8=16$

$8+8=16$

$16=16$

Both sides are equal. Hence proven $x=2$ is solution for our given equation.
