Answer:

x=30

Step-by-step explanation:

The two angles are supplementary. They add to 180

4x+20 + 40 =180

Combine like terms

4x+60 =180

Subtract 60 from each side

4x+60-60 = 180-60

4x = 120

Divide each side by 4

4x/4 = 120/4

x = 30

Which ordered pair in the form (a, b) is a solution of this equation?

Evgen [1.6K]

3a - 4b = 21

check (-2 , -3)

3(-2) -4(-3) =21

-6 +12 = 21

6 does not = 21 so NO

check (0 , 7)

3(0) -4(7) =21

0-28=21

-28 does not equal 21 so NO

check (-3 , -2)

3(-3) -4(-2) =21

-9 +8 = 21

1 does not = 21 so NO

check (7 , 0)

3(7) -4(0) =21

21 = 21
