Use elimination to solve this

The solution is (-7/2 , 3)

Explanation:
#1 : I eliminated the x value which will leave me with the y value.

#2: now that you have the y value,, to look for the x value, pick one equation from the equations given. (I used 2x + 4y = 5)

#3: now put your y value into the equation in order to get the x value. (2x + 4(3) = 5)

#4: now just solve for x.

No i refuse to tell you the answer but the estimate is 10
