Question 282501: what is the answer in (x,y) form?


4x+2y=6
4x-5y=-1

You can put this solution on YOUR website!
Solve using a system of linear equations.
.
4x +2y = 6
4x -5y = -1
.
subtract them
.
7y = 7
y = 1
.
substitute y=1 into the first equation
.
4x +2(1) = 6
4x = 4
x = 1
.
So it appears the solution is (1,1).
.
Graph the two equations it to check, but first you need to get them into y = mx+b form.
.
4x+2y = 6
2y = -4x+6
y = -2x + 3
.
4x -5y = -1
-5y = -4x -1
y = 4/5x + 1/5
.
