Question

What value from set {4,5,6,7,8} makes the equation 6x -3 =45 true? Explain and show all your work.

Answer 1

8

Explanation:

In order for the equation to be true, both sides need to have the same value of 45. So, you need to find what value of x makes that side of the equation equal 45.

To simplify this, I would start by adding 3 to both sides: 6x = 48.

Next, I would divide both sides by 6, giving us x=8.
