4x+y= x
Move all x term to left side
4x-x+y=0
Subtract 4x from 3x
3x+y=0
Move y term to right side
3x= -y
Divide both sides by 3
X= -y/3
Ok so if it's
4x+y= z solve for x
Move y to right side
4x= -y +z
Now divide both by 4 to get x alone
X= -y/4 + z/4
Hey there,
It take 45 min to complete 75% of the wall
1% = 45 / 75
= 0.6
100 % = 0.6 x 100
= 60 min
It takes her 60 mins or 1 hour to finish building the wall.
Hope this helps :))

(X,Y)
The equation that models the difference in the projected enrollments for
public schools and private schools as a function of the number of years
since 1985 is B - R = (-18.53t^2 + 975.8t + 48140) - (80.8t + 8049) = -18.53t^2 + 975.8t + 48140 - 80.8t - 8049 = -18.53t^2 + 895t + 40091
