Answer:

(-3,-1)

Step-by-step explanation:

you can solve this by using elimination.

make the first equation in terms of x by adding 5y to each side and dividing by 2. this will give you x= 2.5y - 0.5.

now substitute this equation into the second one. this will give you:

-3(2.5y - 0.5) + 2y = 7

you solve this for y which will give you y = -1

now that you have the y value you can substitute this in the first equation to get: 2x - 5(-1) = -1

you solve this for x which will give you x = -3
