3(x-y)
The expression -3(x + 10) is equivalent to -3x - 30. This is because when you distribute the -3 to both terms inside the parentheses, you get -3x - 30. The negative sign in front of the 3 applies to both the x and the 10 when distributing.
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

3(x-y)
The expression -3(x + 10) is equivalent to -3x - 30. This is because when you distribute the -3 to both terms inside the parentheses, you get -3x - 30. The negative sign in front of the 3 applies to both the x and the 10 when distributing.
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
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.
In a mathematical sense, 3x isn't an equation, but an expression. In this expression, 3 is a coefficnet.
3x+3-2x=3 x+3=3 x-0
