so I think u you divide something and you times and then you multiply it
The triangle was just flipped so the missing side is going to equal 36, so...
2y+20= 36
(Subtract 20 from each side to isolate the 2y)
2y= 16
(Divide each side by 2 to isolate the variable)
ANSWER:
y= 8
Answer:
y = -2x + 7 and y = x - 2
Step-by-step explanation:
2x + y = 7
y = -2x +7
x - y = 2
-y = -x +2
y = x - 2
