Which pair of x and y values below are the solution to the simultaneous equations? x+2y=6
x-2y=2

x = 4, y = 1

Step 1: use the equations given to find an equation with only 1 term. Here I used x.

(x + 2y) + (x - 2y) = 2x = 6 + 2 = 8

2x = 8

x = 4

Step 2: substitute x = 4 into either given equation. Here I used the first equation x + 2y = 6.

(4 + 2y) = 6

2y = 6 - 4 = 2

y = 1

This solution can also be done by finding y in step 1 or using the other given equation in step 2.

Hope this helped!

step-by-step explanation:

10.50 + taxes which added up to 11.50

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
