Answer: d = 42/r - 6m/r
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
4x - (9 - 3x) = 8x - 1
4x - (9) - -(3x) = 8x - 1
4x - 9 + 3x = 8x - 1
7x - 9 = 8x - 1 (-8x from each side)
-x - 9 = -1 (+9 to each)
-x = 8 (divide -1 from each side)
x = -8
