Use substitution to determine which number(s) from the set {4,5,6} make the equation 7x−6=. (1 point)
By substituting 4 for x in the equation 7x - 6 = 29, we get:
7(4) - 6 = 28 - 6 = 22 which is not equal to 29.
By substituting 5 for x in the equation 7x - 6 = 29, we get:
7(5) - 6 = 35 - 6 = 29 which is equal to 29.
By substituting 6 for x in the equation 7x - 6 = 29, we get:
7(6) - 6 = 42 - 6 = 36 which is not equal to 29.
Therefore, the number(s) from the set {4, 5, 6} that make the equation 7x - 6 = 29 true is only 5.
Use substitution to determine which number(s) from the set {4, 5, 6} make the equation 7x− 6= 29 true. (1 point)
You are right.
