Question

3y+x=3
-2y+5x=15
Help?
(3,0)?

Answer 1

yes.

Answer 2

To verify if your answer is correct here are the steps in solving this:

You want to eliminate one of the unknowns - in this case I chose x. So, multiply one of the equations by -5 to get:

-15y-5x=-15 (this first equation was multiplied by -5)
-2y+5x=15

Adding these two equations you get:

-17y=0
y=(0)/(-17)
y=0 (now substitute this value into one of the equations - I chose the first one)

3y+x=3
(3)(0)+x=3
x=3

So, the solution is x=3 and y=0 which is (3,0)
