Use elimination to find the value of x in the solution for the system of equations. 2x+2y=10,2x-3y=5
jeyben [28]
Elimination

2x+2y=10
2x-3y=5
multiply first equatn by -1

-2x-2y=-10
add to second equation

2x-3y=5
<u>-2x-2y=-10  +
</u>0x-5y=-5
-5y=-5
divide both sides by 5
-y=-1
muitply b-1
y=1

subsitue
2x+2y=10
2x+2(1)=10
2x+2=10
subtract 2
2x=8
divide  2

x=4


x=4
y=1
solution in (x,y) form is
(4,1)
