Division Property of Equality. Always use opposite operation with side that contains variable.
Isolate variable. Divide 4 by 4 to get it by itself.
Now do the same to other side. 12 รท 4 = 3 x = 3
12 = 4 x / / / Divide each side by 4. / / / 3 = x .
To solve for x in the equation 12 = 4 x , divide both sides by 4. This results in x = 3 .
