What is the solution to this system of equations? 5X + 2y =29 X + 4y=13
2 answers:
5x+2y=29
x+4y=13
eliminate y's
multiply top equation by -2 and add to first
-10x-4y=-58
<u>x+4y=13 +</u>
-9x+0y=-45
-9x=-45
divide both sides by -9
x=5
sub baack
x+4y=13
5+4y=13
minus 5 both sides
4y=8
divide both sidse by 4
y=2
x=5
y=2
(x,y)
(5,2)
