First, move like terms on one side. Next, add them and divide. See the attachment for solution.
Answer:
-0.3
Step-by-step explanation:
One way is facing the positive direction and the other way is the negative direction. C is on the negative side and you just needed to count where the black dot was starting from 0 and it got you to -0.3.
Hope this helps and have a great day! =D
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)
