Answer:
-5x=35 divide both sides by 5
-x=7 multiply both sides by -1
x=-7
Answer:
x
-- = y
25
Step-by-step explanation:
Because it is 25% off, x is divided by 25 to get the price.
For example if x was 100, divide it by 25 you get 75, which is y.
Answer:
I think its C
Step-by-step explanation:
Step-by-step explanation:
8x-3y
If you write
, you'll notice this is really just a quadratic equation that can be factorized:
So you have
and
y+1=2x-3
y=2x-4
2x-3=y+1
2x-4=y
y=2x-4
2y+2=4x-6
2y=4x-8
y=2x-4
They are all the same: y=2x-4
