What is the answer to 4(-x + 4) =12

Hey there!

4(-x + 4) = 12

4(-x) + 4(4) = 12

-4x + 16 = 12

SUBTRACT 16 to BOTH SIDES

-4x + 16 - 16 = 12 - 16

CANCEL out: 16 - 16 because it gives you 0

KEEP: 12 - 16 because it helps solve for the x-value

NEW (temporary) EQUATION: -4x = 12 - 16

12 - 16 = -4

NEW EQUATION: -4x = -4

DIVIDE -4 to BOTH SIDES

-4x/-4 = -4/-4

CANCEL out: -4/-4 (the LEFT side) because that gives you 1

KEEP: -4/-4 (the RIGHT side) because it gives you the result of the x-value

x = -4/-4

x = 1

Therefore, your answer is: x = 1

Good luck on your assignment and enjoy your day!

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
