Simplifying
y + -4 = 11
Reorder the terms:
-4 + y = 11
Solving
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + y = 11 + 4
Combine like terms: -4 + 4 = 0
0 + y = 11 + 4
y = 11 + 4
Combine like terms: 11 + 4 = 15
y = 15
___________
45=r+12
We move all terms to the left:
45-(r+12)=0
We get rid of parentheses
-r-12+45=0
We add all the numbers together, and all the variables
-1r+33=0
We move all terms containing r to the left, all other terms to the right
-r=-33
r=-33/-1
r=+33
_________
c-24=12
c-24-(12)=0
c-36=0
We move all terms containing c to the left, all other terms to the right
c=36
