Answer:
3375
Step-by-step explanation:
Multiply the second equation by 2 so that its
6x+4y=-30
then subtract
6x+y=-39
6x+4y=-30
= -3y=-69
divide by -3 to isolate the y
then you get y=23
substitute the y value back into one of the equations to solve for x.
6x+23=-31
solve like you always do and you'll get your x
Congratulations, you solved a problem.

Answer:
x = 20°
Step-by-step explanation:
Given
3x + 80° + 2x = 180° [ being linear pair ]
5x + 80° = 180°
5x = 180° - 80°
5x = 100°
x = 100° / 5
Therefore x = 20°
