Question

Which number, when substituted for x, makes the equation 4x+8=164x+8=16 true?

Answer 1

x = 2

4x + 8 = 16
-8 -8
----------------
4x= 8
-- --
4 4
------------
x=2

Answer 2

`x=2`

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:

`(4x)/(4)=(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.
