m=(b+rm)(1+t)

Solution for m=(b+rm)(1+t) equation:

Simplifying
m = (b + rm)(1 + t)

Multiply (b + mr) * (1 + t)
m = (b(1 + t) + mr(1 + t))
m = ((1 * b + t * b) + mr(1 + t))
m = ((1b + bt) + mr(1 + t))
m = (1b + bt + (1 * mr + t * mr))
m = (1b + bt + (1mr + mrt))
m = (1b + bt + 1mr + mrt)

Solving
m = 1b + bt + 1mr + mrt

Solving for variable 'm'.

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

Add '-1mr' to each side of the equation.
m + -1mr = 1b + bt + 1mr + -1mr + mrt

Combine like terms: 1mr + -1mr = 0
m + -1mr = 1b + bt + 0 + mrt
m + -1mr = 1b + bt + mrt

Add '-1mrt' to each side of the equation.
m + -1mr + -1mrt = 1b + bt + mrt + -1mrt

Combine like terms: mrt + -1mrt = 0
m + -1mr + -1mrt = 1b + bt + 0
m + -1mr + -1mrt = 1b + bt

Reorder the terms:
-1b + -1bt + m + -1mr + -1mrt = 1b + bt + -1b + -1bt

Reorder the terms:
-1b + -1bt + m + -1mr + -1mrt = 1b + -1b + bt + -1bt

Combine like terms: 1b + -1b = 0
-1b + -1bt + m + -1mr + -1mrt = 0 + bt + -1bt
-1b + -1bt + m + -1mr + -1mrt = bt + -1bt

Combine like terms: bt + -1bt = 0
-1b + -1bt + m + -1mr + -1mrt = 0
