Use substitution to determine which number(s) from the set {4, 5, 6} make the equation 7x−6=29 true.(1 point)

Question

x = ?

Answer 1

We can substitute each number from the set {4, 5, 6} into the equation and see which one(s) make it true.

For x = 4:
7(4) - 6 = 28 - 6 = 22, which is not equal to 29.

For x = 5:
7(5) - 6 = 35 - 6 = 29, which is equal to 29.

For x = 6:
7(6) - 6 = 42 - 6 = 36, which is not equal to 29.

Therefore, the number from the set {4, 5, 6} that makes the equation 7x - 6 = 29 true is x = 5.
