Question

5x + 6 = 46. Is x = 8 a solution for this equation? Justify your answer by

showing your step with explanation.

Answer 1

Yes.

Explanation:

`5x+6=46`

To check to see if x = 8 is a solution, replace 'x' with 8 and evaluate.

`5(8)+6=46\\\\40+6=46\\\\\boxed{46=46}`

We get a true statement. This means that x = 8 is a solution to the equation.

Hope this helps.

Answer 2

x = 8

Explanation:

5x + 6 = 46. Is x = 8

5x + 6 = 46

subtract 6 to each side

5x + 6 - 6 = 46 - 6

simplify:

5x = 46 - 6

divide 5 both sides

x = 40 / 5

simplify:

x = 8
