Answer:

Option C step 3

Step-by-step explanation:

we have

-14x-2y=24 ------> equation A

14x+8y=-12 -----> equation B

step 1

Solve the system by elimination

Adds equation A and equation B

-14x-2y=24

14x+8y=-12

---------------------

-2y+8y=24-12

6y=12

The step 1 is correct

step 2

Solve for y

Divide by 6 both sides

6y/6=12/6

y=2

The step 2 is correct

step 3

Find the value of x

substitute the value of y in the equation A

-14x-2(2)=24

-14x-4=24

14x=-4-24

14x=-28

x=-2

The step 3 is not correct

therefore

Petro first make a mistake in Step 3

If the ratio of the measure of the complement of an angle to the measure of its supplement is 1:3, find the measure of the angle
prohojiy [21]
Set up and solve an equation:

3(90-x) = (180-x).  Then  270 - 3x = 180 - x, or   270 - 180 = 2x.
                                                                               90 = 2x, so x = 45 deg.

Is this true?     3(90-45) = (180-45)?  If so, x = 45 degrees is correct.
