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

1 answer

To solve the equation 7x-6=29 using substitution, we can start by isolating 'x' on one side of the equation:

7x - 6 = 29

Add 6 to both sides:

7x = 35

Divide both sides by 7:

x = 5

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