Answer:

Step-by-step explanation:

The given equation is

4x + 24x - 2 = 7(4x +2)

First step is to expand the parenthesis on the left hand side by multiplying each term inside the parenthesis by the term outside the parenthesis. It becomes

4x + 24x - 2 = 28x + 14

Collecting like terms such that the terms containing x will be on the lefthand side and constant terms will be on the right hand side, it becomes

28x - 28x = 14 + 2

0 = 16

0 cannot be equal to 16. Therefore, there is no solution.

The likely error of my friend was

28x - 28x = x

Answer:

  • x +3x = 180
  • x = 45 . . . . . . . choice C
  • 3x = 135 . . . . . choice F

Step-by-step explanation:

Let x represent the measure of the original angle in degrees. Three times its measure is 3x. That will be the supplement if the sum of the two angles is 180°.

  x + 3x = 180 . . . . . . . . . equation for finding the angle

  x = 180/4 = 45 . . . . . .  divide both sides by 4

  3x = 3(45) = 135

The first angle is 45°. The second angle is 135°.
