Evaluate -7(x-4y) when x=-4 and y= -6

-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.
