b(-5v-4)-2b(v+4)=

Solution for b(-5v-4)-2b(v+4)= equation:

Simplifying
b(-5v + -4) + -2b(v + 4) = 0

Reorder the terms:
b(-4 + -5v) + -2b(v + 4) = 0
(-4 * b + -5v * b) + -2b(v + 4) = 0
(-4b + -5bv) + -2b(v + 4) = 0

Reorder the terms:
-4b + -5bv + -2b(4 + v) = 0
-4b + -5bv + (4 * -2b + v * -2b) = 0
-4b + -5bv + (-8b + -2bv) = 0

Reorder the terms:
-4b + -8b + -5bv + -2bv = 0

Combine like terms: -4b + -8b = -12b
-12b + -5bv + -2bv = 0

Combine like terms: -5bv + -2bv = -7bv
-12b + -7bv = 0

Solving
-12b + -7bv = 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), '-1b'.
-1b(12 + 7v) = 0

Ignore the factor -1.
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 '(12 + 7v)' equal to zero and attempt to solve:

Simplifying
12 + 7v = 0

Solving
12 + 7v = 0

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

Add '-12' to each side of the equation.
12 + -12 + 7v = 0 + -12

Combine like terms: 12 + -12 = 0
0 + 7v = 0 + -12
7v = 0 + -12

Combine like terms: 0 + -12 = -12
7v = -12

Add '-7v' to each side of the equation.
7v + -7v = -12 + -7v

Combine like terms: 7v + -7v = 0
0 = -12 + -7v

Simplifying
0 = -12 + -7v
