db+x=7(b-d)

Solution for db+x=7(b-d) equation:

Simplifying
db + x = 7(b + -1d)
bd + x = (b * 7 + -1d * 7)
bd + x = (7b + -7d)

Solving
bd + x = 7b + -7d

Solving for variable 'b'.

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

Add '-7b' to each side of the equation.
bd + -7b + x = 7b + -7b + -7d

Reorder the terms:
-7b + bd + x = 7b + -7b + -7d

Add '-1x' to each side of the equation.
-7b + bd + x + -1x = -7d + -1x

Combine like terms: x + -1x = 0
-7b + bd + 0 = -7d + -1x
-7b + bd = -7d + -1x

Reorder the terms:
-7b + bd + 7d + x = -7d + 7d + -1x + x

Combine like terms: -7d + 7d = 0
-7b + bd + 7d + x = 0 + -1x + x
-7b + bd + 7d + x = -1x + x

Combine like terms: -1x + x = 0
-7b + bd + 7d + x = 0
