Can you anser number 9

Step-by-step explanation:

Equations

Let's call

x = measure of angle 1

y = measure of angle 2

The angles are supplementary, thus their sum is 180°:

x + y = 180        [1]

It's also known that one angle (x) is 7° more than twice the other (y), thus:

x = 7+ 2y        [2]

Substituting [2} in [1]:

7+ 2y + y = 180

Operating:

7+ 3y = 180

Subtracting 7:

3y = 180 - 7 = 173

Dividing by 3:

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
