subtract eq2 from 1
0=(2/5+2.5)x -17.7-20
0=(2.9x)-37.7
x=37.7/2.9
for y, put that value of x into either equation, and solve for y.
Solve the following system of equations. You will type your x value in the first part and the y value in the second part of the question. If the answer is no solution then type NS in both parts and if the the answer is infinite solutions then type I in both parts.
y = 2/5 x- 17 7/10
y = -5/2 x + 20
What is the x value?

Since the two y values must be the same ....
2/5 x- 17 7/10 = -5/2 x + 20
2x/5 - 177/10 = -5x/2 + 20
I suggest we multiply each term by 10
4x - 177 = -25x + 200
take over , (the x value is a whole number, but the y isn't)
