To solve the equation x−15=12−8 using substitution, we first need to simplify both sides of the equation.
x - 15 = 12 - 8
x - 15 = 4
Next, we need to solve for x by adding 15 to both sides of the equation.
x - 15 + 15 = 4 + 15
x = 19
Therefore, Mikayla is correct. The answer to the equation x−15=12−8 is x=19..
