  1. Combine like terms: Step Title: Combine like terms\newlineConcise Step Description: Group and add the coefficients of like terms to simplify the expression.\newlineStep Calculation: Combine the coefficients of xx terms: 3x+2x=5x3x + 2x = 5x. Combine the coefficients of yy terms: 2y+7y=9y2y + 7y = 9y. Combine the constant terms: 2+7=5-2 + 7 = 5.\newlineStep Output: Simplified expression: 5x+9y+55x + 9y + 5
