When you solve proportions, you have to cross multiply.
9 x
--- = --- Multiply each numerator by the opposite denominator.
11 22
(9)(22) = 11x Then, multiply.
198 = 11x Then, divide.
18 = x
you add 78 plus 37 then subtract from 180
Answer:
(1,1)
Step-by-step explanation:
Answer:
Okay, so. What I'd do is this.

Then I'd combine like terms.
So:

Once you've got 6x, you subtract 6 from 180.

Now all that's left to do is divide each side by 6 to get x.
X should be 29.
Step-by-step explanation:
You know that adding the equations will give you 180 because you know they're supplementary.
