Can you me solve systems of equations by elimination step by step -5x+9y=-12 3x+2y=22

Step-by-step explanation:

First solve -5x+9y=-12 for x:

-5x+9y=-12

-5x+9y-9y=-12-9y

-5x=-12-9

-5x=-9-12

-5x/-5=-9/5-12/-5

x=9/5y+12/6

Substitute x into an equation

3(-9/5y+12/6)+2y=22

37/5y+36/5=22

37/5y+36/5-36/5=22-36/5

37/5y=74/5

37/5y/37/5=74/5/37/5

y=2

Substitute y in x=-9/5y+12/6

9/5(2)+12/6

x=6

Solution Set: (6,2)

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

i dont get the question
