Answer:
x = 23
y = 128
Step-by-step explanation:
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.
98 = 2x + 3x - 17
115 = 5x
x = 23
Angles 3x - 17 and y form a linear pair, so they are supplementary.
3x - 17 + y = 180
3(23) - 17 + y = 180
69 - 17 + y = 180
52 + y = 180
y = 128
Answer:
-5x - 8y = -5
Step-by-step explanation:
Whenever we two equations, we are essentially just adding the left sides up and then the right sides up. Here, let's write these into one whole big equation:
(4x - 4y) + (-9x - 4y) = -2 + (-3)
Taking the parentheses out, we have:
4x - 4y - 9x - 4y = -2 - 3
Combine like terms:
4x - 9x - 4y - 4y = -5
-5x - 8y = -5
Hope this helps!
