Answer/Step-by-step explanation:
2x-5y=9
Add 5y to both sides of the equation.
2x=9+5y
Divide each term by 2 and simplify.
Divide each term in 2x=9+5y by 2
Cancel the common factor of 2.
Divide x by 1.

3x+4y=2
Add 4y to both sides of the equation
3x=2+4y
Divide each term by 3 and simplify.
Divide each term in 3x=2+4y by 3.
Cancel the common factor of 3.
Divide x by 1.
<em>In decimal form, a = 114.5; b = 25.5</em>
We will write this as a system of equations, where and
are the two angles.
We will use substitution to solve this system. We know what equals, so we plug that into the second equation.
Combine the like terms.
Add on both sides.
Divide both sides by .
Now just subtract that from .
