Solve for x in the diagram below.
100°
20
2=

x = 40

Step-by-step explanation:

The answer is x = 40. This is because the two angles that are x are 1. congruent and 2. supplementary with 100° (They all add up to 180°). I can show this with a simple equation.

1. 2x + 100 = 180

2. 2x = 80

3. x = 40

x= −1/5y + 2/5

Step-by-step explanation:

Let's solve for x.

y=−5x+2

Step 1: Flip the equation.

−5x+2=y

Step 2: Add -2 to both sides.

−5x+2+−2=y+−2

−5x=y−2

Step 3: Divide both sides by -5.
