Y= 3x+13
y=x-3
How do you solve this equation?

x=-8, y=-11. (-8, -11).

Step-by-step explanation:

y=3x+13

y=x-3

3x+13=x-3

3x-x+13=-3

2x+13=-3

2x=-3-13

2x=-16

x=-16/2

x=-8

y=-8-3=-11

answer: there are 453.592 grams in a pound.

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
