5x- 3/2x= -4 -7/2
10/2 x - 3/2x= -8/2 -7/2
7/2x= -15/2
7x= -15
x= -15/7
Answer: 
<u>Step-by-step explanation:</u>
x - 2 = -4y → x = 2 - 4y
3x + 2y = 11
3(2 - 4y) + 2y = 11 <em>replaced "x" with (2 - 4y)</em>
6 - 12y + 2y = 11 <em>distributed "3" on left side</em>
<em> </em>6 - 10y = 11 <em>added like terms (-12y + 2y)</em>
- 10y = 5 <em>subtracted "6" from both sides</em>
y
<em>divided both sides by -10</em>
Next, solve for x:
x = 2 - 4y

= 2 + 2
= 4
Answer:
15°
Step-by-step explanation:
sorry if I'm wrong but I think you need to add up all the ° and then subtract that number from 100 to get your answer in which in this case the answer would be 15°
