If it's not what You are looking for type in the equation solver your own equation and let us solve it.

Solution for =3a(b-c) equation:


Simplifying
0 = 3a(b + -1c)
0 = (b * 3a + -1c * 3a)
0 = (3ab + -3ac)

Solving
0 = 3ab + -3ac

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-3ab' to each side of the equation.
0 + -3ab = 3ab + -3ab + -3ac
Remove the zero:
-3ab = 3ab + -3ab + -3ac

Combine like terms: 3ab + -3ab = 0
-3ab = 0 + -3ac
-3ab = -3ac

Add '3ac' to each side of the equation.
-3ab + 3ac = -3ac + 3ac

Combine like terms: -3ac + 3ac = 0
-3ab + 3ac = 0

Factor out the Greatest Common Factor (GCF), '3a'.
3a(-1b + c) = 0

Ignore the factor 3.

Subproblem 1

Set the factor 'a' equal to zero and attempt to solve: Simplifying a = 0 Solving a = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a = 0

Subproblem 2

Set the factor '(-1b + c)' equal to zero and attempt to solve: Simplifying -1b + c = 0 Solving -1b + c = 0 Move all terms containing a to the left, all other terms to the right. Add 'b' to each side of the equation. -1b + b + c = 0 + b Combine like terms: -1b + b = 0 0 + c = 0 + b c = 0 + b Remove the zero: c = b Add '-1c' to each side of the equation. c + -1c = b + -1c Combine like terms: c + -1c = 0 0 = b + -1c Simplifying 0 = b + -1c The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Solution

a = {0}
