The expression goes like this: 2x+y+5-3. x and y are variables so we cannot perform unless we have a linear or simultaneous or as such equations.But operation can be performed if like terms are present, but in your problem the answer will be: 2x+y+2
to simplify an expression means to take all the like terms and make them one. for example if the expression is 2x+5x+1x-4 , you would simplify it by adding 2x,5x,&1x because they are all alike... it would become 8x-4
It is an expression.
5x - 8a + 4a - 2x + a = 3x - 3a
x - 2x + 3 = 3 - x
2x
It is 16y+23x simplified
4x + 3y - 2x - 7y2x - 4y
2x plus 5x simplified is 7x.

2x + 4x + 3 = 6x + 3
6x + 9 + 2x = 8x + 9
to simplify an expression means to take all the like terms and make them one. for example if the expression is 2x+5x+1x-4 , you would simplify it by adding 2x,5x,&1x because they are all alike... it would become 8x-4
3x+3-2x=3 x+3=3 x-0
It is an expression.
It can be factored as 18(5-2x^2)
Actually, 2x + 3y + z is an expression, because it is a mathematical noun.
