is the x before the 21 is multiplication then I need a value for x to solve, but for the sake of an answer I will assume it's 6x-12=21 6x-12=12 +12 +12 6x=24 /6 /6 x=4 is the x before the 21 is multiplication then I need a value for x to solve, but for the sake of an answer I will assume it's 6x-12=21 6x-12=12 +12 +12 6x=24 /6 /6 x=4
3x + 6 = 27.Subtract 6 from both sides: 3x = 27 - 6 = 21.Divide both sides by 3: x = 21/3 = 7.x = 7
If: 3x-3 = 7x+21 Then: x = -6
I'm pretty sure this isn't right but if x=6 and y=15 then it is just 6 + 15 which is 21.
1 x 42 2 x 21 3 x 14 6 x 7
3.5 x 6 = 21
6/100 X n = 21 .06 X n = 21 n = 21/.06 = 350
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factor pairs of 42 are 1 x 42, 2 x 21, 3 x 14, and 6 x 7.1, 2, 3, 6, 7, 14, 21, 42.1 2 3 6 7 21 14 42

1 x 21 = 21 2 x 21 = 42 3 x 21 = 63 4 x 21 = 84 5 x 21 = 105 6 x 21 = 126 7 x 21 = 147 8 x 21 = 168 9 x 21 = 189 10 x 21 = 210 11 x 21 = 231 12 x 21 = 252 ...
6 x 3 = 18 7 x 3 = 21 therefore 6 to 7 = 18 to 21
(-7 x -3) + (-6) = 21 - 6 = 15
