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
