Question 482848

(3x  - 5) + (15 - x) + (2x - 3) = 35


3x - 5 + 15 - x + 2x - 3 = 35


3x - x + 2x - 5 + 15 - 3 = 35


4x + 7 = 35


4x = 28


x = {{{28/4}}} or {{{highlight(7)}}} units


Side that's "3x - 5" = 3(7) - 5 = 21 - 5 = {{{highlight_green(16)}}} units.


Side that's "15 - x" = 15 - 7 = {{{highlight_green(8)}}} units.


Side that's "2x - 3" = 2(7) - 3 = 14 - 3 = {{{highlight_green(11)}}} units.
