13 + 53 = 66
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
66 times 6 equals 396.

88 + 5y - y2 66 - 3y + y2 Subtract: 22 + 8y -2y2
(-19+66)=(66-19)=47
66 plus -62 = 4
It is equal to 66

You can use a Calculator online and since I did… 55.e + 66 = 215.505500565. Im sorry if this isn’t what you are looking for and plus I have no other Ideas to solve it.
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
