use substitution to determine which number from the set {6,7,8,9} makes the equation 63 + x = 9 true. [standerd PAR.7.1}

Answer 1

To solve the equation 63 + x = 9 using substitution, we substitute each number from the given set {6, 7, 8, 9} for x and see which one makes the equation true.

For x = 6:
63 + 6 = 69 ≠ 9

For x = 7:
63 + 7 = 70 ≠ 9

For x = 8:
63 + 8 = 71 ≠ 9

For x = 9:
63 + 9 = 72 ≠ 9

None of the numbers from the set {6, 7, 8, 9} make the equation 63 + x = 9 true.
