3(y + 4) - (x - 1)
x = 3
y = 2
First plug in the numbers into the variables. Or plug in 3 for "x" and 2 for "y" in the equation.
3(y + 4) - (x - 1)
3(2 + 4) - (3 - 1) Simplify the numbers in the parentheses
3(6) - (2)
18 - 2 = 16
Put the values of x = 3 and y = 2 to the expression 3(y + 4) - (x - 1):
3(2 + 4) - (3 - 1) = 3(6) - (2) = 18 - 2 = 16
