Radical (3x) = radical(x) * radical(3).
3(x-y)
If you mean -3(x+10) then it is -3x-30
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
3x+3-2x=3 x+3=3 x-0
6 radical 6
3x + 3x + 3x = 3* (3x) = 9x

3(x-y)
If you mean -3(x+10) then it is -3x-30
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
In a mathematical sense, 3x isn't an equation, but an expression. In this expression, 3 is a coefficnet.
when you say 3x, you mean that there are 3 x's. Multiplication implies repeated addition, so three x's added is x+x+x, which equals 3x.
3x+3-2x=3 x+3=3 x-0
