Answer:
-4y=11x-33
Step-by-step explanation:
3x-2y-16=-17+14x+2y
-2y-2y=14x-3x-17+16
-4y=11x-33
The four interior angles make a sum of 360
x+10+3x+2x+x=360
7x=350
x=50
Answer:
x = 2, y = 3
Step-by-step explanation:
5x – 4y = -2
2x + 4y = 16
<em></em>
<em>Solve by elimination. (-4y and +4y gives 0)</em>
7x = 14
x = 2
<em>Substitute 2 in one of the equations in order to find y.</em>
5(2) - 4y = -2
10 - 4y = -2
-4y = -12
y = 3
x = 2, y = 3
hope this helps!! p.s. i really need brainliest :)
