It is equivalent to 15x+10
5x + 4
It means whatever x is, multiply it by 3 and add 10
5x+3x-6x+4x+2x-x+10 This expression can be simplified to: 7x+10 (7 being the coefficient of x)
It is an expression that can be simplified to: 3x-20
It is equivalent to 15x+10
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
It is equivalent to: 3x+6+5 = 3x+11
5x + 4
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.
It is 22/10*(3x + 2)
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.

3x + 3x + 3x = 3* (3x) = 9x
3x-3y?
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.
It means whatever x is, multiply it by 3 and add 10
