So you find 15% of the $108 which is $16.20 you do this by 15/100*108. Then you add $16.20 to 108 and you get $124.20.
So the answer is $124.20
You can using any equation you want to solve for one of the variables. For instance, if you want to solve for x you turn one of the equations so y is by its self
<span>
2x + 3y = 5
4x - y =3
I am going to use </span>4x - y =3
-y = -4x + 3
y = 4x -3
Now you can substitute 4x - 3 for y in 2x + 3y = 5 and solve for x
2x + 3y = 5
2x + 3(4x - 3) = 5
Answer:
y = .1x + .16
↓
y= .1x + .2
hope it helps
Step-by-step explanation:
