Hi there!
There shouldn't be roots in solutions. but sometimes if you use roots to simplify then roots can be in solutions.
Hope this helps you,

Considering Reid ate 1/4 of the pie and Joe ate 1/3 of the pie, we have to bring this to their common denominator. In this case that is 12.
1/4 + 1/3 = ?
(1 * 3)/12 + (1*4)/12 =
3/12 + 4/12 =
(3 + 4)/12 =
7/12
But this is the amount of the pie that both Reid and Joe ate.
To calculate the remaining amount we have to imagine our pie was still whole (12/12)
and substract what they both ate (7/12):
12/12 - 7/12 = 5/12
Only 5/12 of the pie was left, a little less than half of it :)
Answer:
x= 3
y= 3
Step-by-step explanation:
Step: Solve−x+y=0 for y:
−x+y=0
−x+y+x=0+x (Add x to both sides)
y=x
Step: Substitute x for y in 4x−3y=3:
4x−3y=3
4x−3x=3
x=3 (Simplify both sides of the equation)
Step: Substitute 3 for x in y=x:
y=x
y=3
