Add them together and divide by the number of values (4).
3x + 15y = 33 4x - 3y = 66 3x + 15y = 33 divide by 3 to both sides x + 5y = 11 subtract 5y from both sides x = 11 - 5y 4x - 3y = 66, replace x with 11- 5y 4(11 - 5y) - 3y = 66 44 - 20y - 3y = 66 subtract 44 from both sides -23y = 22 divide by -23 to both sides y = -22/23 x = 11 - 5y replace y with -22/23 x = 11 - 5(-22/23) x = 11 + 110/23 x = (11*23 + 110)/23 x = 363/23
11% of 23 = 11% * 23 = 0.11 * 23 = 2.53
2*23/11 = 46/11 = 42/112*23/11 = 46/11 = 42/112*23/11 = 46/11 = 42/112*23/11 = 46/11 = 42/11
take 7 then divide by 11 get an answer then divide that answer by 21
23/12 = 1 11/12 23/8 = 2 7/8 = 2.875
