Try out all of your options by filling the the x and y values from each option. You can use either of the two equations to solve
1) 2(2)+3(3) does not equal 5
2) 2(3)+3(2) does not equal 5
3) 2(3)+3(-2) does not equal 5
4) 2(-2)+3(3) equals 5
4.5) Double check your answer by doing the same thing for the second equation // 3(-2)+2(3) does equal zero.

Answer:
a = 60°
60°, 60°, 120°, and 120°.
Step-by-step explanation:
Sum of interior angles of a quadrilateral = 360°
Therefore:
a° + a° + 2a° + 2a° = 360°
Add like terms
6a = 360
Divide both sides by 6
a = 60
2a = 2(60) = 120°.
Angle measure from least to greatest are 60°, 60°, 120°, and 120°.
Answer:
Hans has done a mistake in the second step.
The correct answer is:
5x^2+13x-6=0
5x^2+15x-2x-6x=0 - 5. -6=-30 -30=15. -2
5x(1+3x)-2x(1+3x)=0
(5x-2x)(1+3x)=0
5-2x=0 1+3x=0
x=5/2 x=-1/3
The first choice is substitution because G s being substituted by C
