An unknown number y is 10 more than an unknown number x. the number y is also x less than 3. the equations to find x and y are shown below. y = x + 10 y = –x + 3 which of the following statements is a correct step to find x and y? (4 points) add the equations to eliminate x. multiply the equations to eliminate y. write the points where the graphs of the equations intersect the x-axis. write the points where the graphs of the equations intersect the y-axis.

If you add the two equations, you will indeed eliminate x:

the answer is  A

Step-by-step explanation:

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
