I dunno if this is right or not but x=20.
Answer:
x=-11, y=-5. (-11, -5).
Step-by-step explanation:
2y=2x+12
y=-2-3
-----------------
simplify 2y=2x+12 into y=x+6
y=-5
------------------
-5=x+6
x=-5-6=-11
10=2x5
60=2x2x3x5
2x2x5x3=60
i think to do this you need lcm but im not sure
L = 3x width
2L + 2W = 16 units
2(3W) + 2W = 16 units
8W = 16 units
Width = 2 units
