3 and 7 multiplies to 21 and equals to 10
well -24 + 21 = -3
3x-10 equals 24; add 10 to both sides 3x equals 34; divide by 3 x=11.333 or 11 1/3
X - 7/8 = - 5/12 let's get those denominators the same; 24 looks right. X - 3*7/3*8 = - 5*2/2*12 X - 21/24 = - 10/24 add 21/24 to both sides X = 11/24 check 11/24 - 21/24 = - 10/24 - 10/24 = - 10/24 or - 5/12 = - 5/12

9 times 7/3 = 21
If: 24 = 6-x-3 Then: x = -21
x-3-7x=21 -6x=21+3 6x=-24 x=-4
2x-3 = 21+10x 2x-10x = 21+3 -8x = 24 x = -3

24 hours in a day subtract 3 and it equals 21 so the answer is 21
