Answer:
a = 6
Subtract 2a from 5 a .
3 a − 6 = 12
Move all terms not containing a to the right side of the equation.
Add 6 to both sides of the equation.
3 a = 12 + 6
Add 12 and 6 .
3 a = 18
Divide each term by 3 and simplify.
Divide each term in 3 a = 18 by 3 .
3 a/ 3 = 18 /3
Reduce the expression by cancelling the common factors.
Cancel the common factor.
(3 a /3) *gone* = 18/ 3
Divide a by 1 .
a = 18/ 3
Divide 18 by 3 .
a = 6
