Answer:
x = 50°
Step-by-step explanation:
130 and x are adjacent angles on a straight line and sum to 180° , so
x + 130° = 180° ( subtract 130° from both sides )
x = 50°
$21 I believe (it's 1 am where I am so I'm not 100% sure but I think it's correct)
5x+3y=9
2x-3y=5
5x+2x=9+5
7x=14
14/7x= 2
x=2
sub it in so you get y
5(2)+3y=9
10+3y=9 (-10 to get rid of it)
3y=-1
3y/-1= - 1/3
x= 2 y= - 1/3
Answer: x=14 and y=5
