Answer:
the correct answer is option D
It's been a while since I've done algebra but the answer that I got was x=4
Answer:
<em>x = 15 ; y = 53 </em>
Step-by-step explanation:
(7x + 18)° + (4x - 3)° = 180°
11x + 15 = 180
11x = 165
<em>x = 15</em>
(2y + 17)° + (4(15) - 3)° = 180°
2y + 17 + 57 = 180
2y = 106
<em>y = 53</em>
