Відповідь:
8x+6y+5x+17y = 13x + 23y
(3x-8y)+(6x+5y) = 3x + 6x - 8y + 5y = 9x - 3y
(8x-9y)-(10x-11y) = 8x - 9y - 10x + 11y = -2x + 2y
4(3x-5y)-5(3x-6y) = 12x - 20y - 15x + 30y = -3x + 10y

Verified answer
Відповідь:
8x+6y+5x+17y = 13x + 23y
(3x-8y)+(6x+5y) = 3x + 6x - 8y + 5y = 9x - 3y
(8x-9y)-(10x-11y) = 8x - 9y - 10x + 11y = -2x + 2y
4(3x-5y)-5(3x-6y) = 12x - 20y - 15x + 30y = -3x + 10y
