Answer:
-140
Step-by-step explanation:
Plug in -4 for x, and -6 for y, in the expression:
-7(x - 4y) = -7((-4) - 4(-6))
Simplify. First, solve the terms within the parenthesis. Multiply:
-7((-4) (-4 * -6))
-7((-4) (+24))
-7(-4 + 24)
Solve the parenthesis. Add:
-7(20)
Fully simplify.
-7 * 20 = -140
-140 is your answer.
