X+(X*0.12)-[(X+(X*0.12))*0.05]=Y

Solution for X+(X*0.12)-[(X+(X*0.12))*0.05]=Y equation:

Simplifying
X + (X * 0.12) + -1[(X + (X * 0.12)) * 0.05] = Y

Reorder the terms for easier multiplication:
X + (0.12X) + -1[(X + (X * 0.12)) * 0.05] = Y

Reorder the terms for easier multiplication:
X + (0.12X) + -1[(X + (0.12X)) * 0.05] = Y

Combine like terms: X + (0.12X) = 1.12X
X + (0.12X) + -1[(1.12X) * 0.05] = Y

Remove parenthesis around (1.12X)
X + (0.12X) + -1[1.12X * 0.05] = Y

Reorder the terms for easier multiplication:
X + (0.12X) + -1[1.12 * 0.05X] = Y

Multiply 1.12 * 0.05
X + (0.12X) + -1[0.056X] = Y

Remove brackets around [0.056X]
X + (0.12X) + -1 * 0.056X = Y

Multiply -1 * 0.056
X + (0.12X) + -0.056X = Y

Combine like terms: X + (0.12X) = 1.12X
1.12X + -0.056X = Y

Combine like terms: 1.12X + -0.056X = 1.064X
1.064X = Y

Solving
1.064X = Y

Solving for variable 'X'.
