Answer:
y = 4 / x = 2
Step-by-step explanation:
Insert x equation for variable x
y = 2(-y+6)
simplify
y= -2y + 12
add 2y to both sides
3y= 12
divide both sides by 3
y = 4
Insert 4 as y in y =2x
4=2x
divide both sides by 2
x=2
False, it's the other way around: you divide the numerator by the denominator.
For example, to evaluate
you divide 8 by 15:

The height of the rectangle is 15 while the base is 3.
15+15+3+3=36cm
