If you mean the multiplication of 3 by 6, then you can express it as columns by rows of dots, for example. Either 3 columns with 6 rows or vice versa. Then you count all the dots. The result would be 18. You can also use a calculator. I said "if you mean" because by the way you wrote the expression it could also seem like an algebraic expression where you need to find x, but then it seems incomplete so I wouldn't know how to help you.
If you meant 3x=6 and want to solve for x, then divide both sides of the equation by 3.
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
Solve:4 - 3x = 104 - 3x - 4 = 10 - 4-3x = 6-3x/-3 = 6/-3x = -2Check:4 - (3 x -2) = 104 - (-6) = 104 + 6 = 1010 = 10
7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
6 - 3x = 4 - 2x 6 = x + 4 x = 2 Check it. 6 - 6 = 4 - 4 It checks.
wat does 2y-3x-6 equal
6x-3x =6 3x=6 so 6 divided by 3 = 2
3x-2y=6 -2y=-3x+6 y=1.5x-3
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
3x+2y=6 2y=-3x+6 y=-1.5x+3
18=3(3x-6)
3x + 4 = 5x - 6 -3x -3x 4 = 2x - 6 +6 +6 10 = 2x 5 = x
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
3x+6 = x-10 3x-x = -10-6 2x = -16 x = -8
5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4
Solve:4 - 3x = 104 - 3x - 4 = 10 - 4-3x = 6-3x/-3 = 6/-3x = -2Check:4 - (3 x -2) = 104 - (-6) = 104 + 6 = 1010 = 10
