-3b[2c+4-5t+(-4)]=

Solution for -3b[2c+4-5t+(-4)]= equation:

Simplifying
-3b[2c + 4 + -5t + (-4)] = 0
-3b[2c + 4 + -5t + -4] = 0

Reorder the terms:
-3b[4 + -4 + 2c + -5t] = 0

Combine like terms: 4 + -4 = 0
-3b[0 + 2c + -5t] = 0
-3b[2c + -5t] = 0
[2c * -3b + -5t * -3b] = 0
[-6bc + 15bt] = 0

Solving
-6bc + 15bt = 0

Solving for variable 'b'.

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

Factor out the Greatest Common Factor (GCF), '3b'.

Ignore the factor 3.
Subproblem 1
Set the factor 'b' equal to zero and attempt to solve:

Simplifying
b = 0

Solving
b = 0

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

Simplifying
b = 0
Subproblem 2
Set the factor '(-2c + 5t)' equal to zero and attempt to solve:

Simplifying
-2c + 5t = 0

Solving
-2c + 5t = 0

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

Add '2c' to each side of the equation.
-2c + 2c + 5t = 0 + 2c

Combine like terms: -2c + 2c = 0
0 + 5t = 0 + 2c
5t = 0 + 2c
Remove the zero:
5t = 2c

Add '-5t' to each side of the equation.
5t + -5t = 2c + -5t

Combine like terms: 5t + -5t = 0
0 = 2c + -5t

Simplifying
0 = 2c + -5t
