use substitution to determine which number from the set {6,7,8,9} makes the equation 63 + x = 9 true. [standerd PAR.7.1}
To solve the equation 63 + x = 9 using substitution, you would substitute each number from the set {6, 7, 8, 9} for x and check if the equation becomes true.
Let's try each number one by one:
1. Substitute x = 6:
63 + 6 = 69, which is not equal to 9.
2. Substitute x = 7:
63 + 7 = 70, which is not equal to 9.
3. Substitute x = 8:
63 + 8 = 71, which is not equal to 9.
4. Substitute x = 9:
63 + 9 = 72, which is not equal to 9.
None of the numbers from the set {6, 7, 8, 9} make the equation 63 + x = 9 true.
Therefore, there is no solution to the equation.
