Solution for r(b-4)+z(b-4)= equation:


Simplifying
r(b + -4) + z(b + -4) = 0

Reorder the terms:
r(-4 + b) + z(b + -4) = 0
(-4 * r + b * r) + z(b + -4) = 0

Reorder the terms:
(br + -4r) + z(b + -4) = 0
(br + -4r) + z(b + -4) = 0

Reorder the terms:
br + -4r + z(-4 + b) = 0
br + -4r + (-4 * z + b * z) = 0

Reorder the terms:
br + -4r + (bz + -4z) = 0
br + -4r + (bz + -4z) = 0

Reorder the terms:
br + bz + -4r + -4z = 0

Solving
br + bz + -4r + -4z = 0

Solving for variable 'b'.

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

Add '4r' to each side of the equation.
br + bz + -4r + 4r + -4z = 0 + 4r

Combine like terms: -4r + 4r = 0
br + bz + 0 + -4z = 0 + 4r
br + bz + -4z = 0 + 4r
Remove the zero:
br + bz + -4z = 4r

Add '4z' to each side of the equation.
br + bz + -4z + 4z = 4r + 4z

Combine like terms: -4z + 4z = 0
br + bz + 0 = 4r + 4z
br + bz = 4r + 4z

Reorder the terms:
br + bz + -4r + -4z = 4r + -4r + 4z + -4z

Combine like terms: 4r + -4r = 0
br + bz + -4r + -4z = 0 + 4z + -4z
br + bz + -4r + -4z = 4z + -4z

Combine like terms: 4z + -4z = 0
br + bz + -4r + -4z = 0
