Answer 2

multiply the first equation by 5 to give
-5x + 10y = 30 ---- (1)
5x + 5y = 15------(2)

Answer 3

now adding these 2 equations will eliminate x and you can then find the value of y
finally plug this value of y into the second equation and solve for x

Answer 4

I'm confused

Answer 5

can you add the 2 equations
-5x + 10y = 30
5x + 5y = 15

adding 5x and -5x gives zero so that eliminates the x

10y + 5y = 15y
and
30+15 = 45

so
15y = 45

what is value of y?

Answer 6

15y = 45
divide the 15y and the 45 by 15 - what do you get?

Answer 7

y=3
