To solve for x, we will isolate it on one side of the equation by performing inverse operations.
Starting with:
3x - 3 = -18
Add 3 to both sides:
3x - 3 + 3 = -18 + 3
Simplify:
3x = -15
Divide both sides by 3:
3x/3 = -15/3
Simplify:
x = -5
Therefore, the solution is x = -5.
3x -3 = -18

R/2 - 6 = 14
To solve for r, we will isolate it on one side of the equation by performing inverse operations.
Starting with:
R/2 - 6 = 14
Add 6 to both sides:
R/2 - 6 + 6 = 14 + 6
Simplify:
R/2 = 20
Multiply both sides by 2:
2 * R/2 = 2 * 20
Simplify:
R = 40
Therefore, the solution is r = 40.
Starting with:
R/2 - 6 = 14
Add 6 to both sides:
R/2 - 6 + 6 = 14 + 6
Simplify:
R/2 = 20
Multiply both sides by 2:
2 * R/2 = 2 * 20
Simplify:
R = 40
Therefore, the solution is r = 40.
12 + 4m = 25
To solve for m, we will isolate it on one side of the equation by performing inverse operations.
Starting with:
12 + 4m = 25
Subtract 12 from both sides:
12 - 12 + 4m = 25 - 12
Simplify:
4m = 13
Divide both sides by 4:
4m/4 = 13/4
Simplify:
m = 13/4 or m = 3.25
Therefore, the solution is m = 3.25 (or m = 13/4).
Starting with:
12 + 4m = 25
Subtract 12 from both sides:
12 - 12 + 4m = 25 - 12
Simplify:
4m = 13
Divide both sides by 4:
4m/4 = 13/4
Simplify:
m = 13/4 or m = 3.25
Therefore, the solution is m = 3.25 (or m = 13/4).
