It is an expression that is equivalent to -3x-19.
-9
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-3y?
It is an expression that is equivalent to -3x-19.
The expression equivalent to 5 plus 3x plus 10 can be simplified by combining the constant terms. Adding 5 and 10 gives 15, so the expression simplifies to 3x + 15. Therefore, the equivalent expression is 3x + 15.
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
Radical (3x) = radical(x) * radical(3).
To find an equivalent expression to ( 4 + 3(5 + x) ), first apply the distributive property: ( 3(5 + x) = 15 + 3x ). Then, add this result to 4: ( 4 + 15 + 3x = 19 + 3x ). Thus, an equivalent expression is ( 19 + 3x ).
It is equivalent to 15x+10

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.
