12-3m=18
12-3m=18
-3m + 12 - 12 = 18 - 12
-3m = 6
m = -2
Check:
12 + 6 = 18
Do you wish to solve for m?
subtract 12 from both sides.
12-12-3m = 18-12
combine terms
-3m= 6
multiply by -1
3m = -6
divide both sides by 3
3m/3 = -6/3
m = -2
check:
12-3(-2) = 18
12+6=18
18=18
To solve the equation 12 - 3m = 18, we need to isolate the variable m.
Step 1: Start by subtracting 12 from both sides of the equation to move the constant term to one side:
12 - 12 - 3m = 18 - 12
Simplifying this yields:
-3m = 6
Step 2: Next, divide both sides of the equation by -3 to solve for m:
(-3m) / -3 = 6 / -3
This simplifies to:
m = -2
So, the solution to the equation 12 - 3m = 18 is m = -2.
