Let x = original price in dollars

x is the original price
9% of this original price is equal to 0.09x

subtract: x - 0.09x = 0.91x

The discount price is equal to 0.91x and it's equal to 90 dollars, so they must be the same value. Ie.

0.91x = 90
0.91x/0.91 = 90/0.91
x = 98.9010989
x = 98.90

So the original price is $<span>98.90</span>

We can use vertical opposite angles. Which means the opposite angles where 2 lines intersects is the same.
3x + 50 = 6x - 10 (vert. Opp. Angles)
3x = 6x - 60
-3x = - 60
X = 20°

Answer:

x =  - 3

y = 1

Step-by-step explanation:

Write the system

3x - y =  - 10

x + y =  - 2

Solve by Elimination.

multiply the second equation by -3.

3x - y =  - 10

-3x   - 3y =  6

Add the Equations.

- 4y =  - 4

y = 1

Plug this back in one of the equations.

x + 1 =  - 2

x =  - 3
