66 plus 66 plus 66 plus 66 plus 66 plus 66 equals?
66 times 6 equals 396.
What is the answer to 3x plus 15y equals 33 and 4x-3y equals 66 using the substitution method?
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
What is 12x-60 plus 6 equals 1x plus 9 plus 2x?
False12x - 66 = 3x + 912x - 3x = 9 + 669x = 65x = 7.22Check:12(7.22) - 60 + 6 = 1(7.22) + 9 + 2(7.22)86.64 - 66 = 7.22 + 9 + 14.4420.64 = 30.66
