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
That depends what the value of x is.
If you have a expression that goes; 2x + 5x etc etc Simplifying the like terms is 7x 2x and 5x are like terms, but 2y and 2x are not. The variable needs to be the same.
A quadratic expression in the variable x.
Yes, since the expression contains more than one variable, then 2x+5y+2 is a polynomial.
the letter in 2x+6. The variable is the x.
2x
It is 16y+23x simplified
-3
4x + 3y - 2x - 7y2x - 4y
That depends what the value of x is.
If you have a expression that goes; 2x + 5x etc etc Simplifying the like terms is 7x 2x and 5x are like terms, but 2y and 2x are not. The variable needs to be the same.
A quadratic expression in the variable x.
x + 2x
Yes, since the expression contains more than one variable, then 2x+5y+2 is a polynomial.
the letter in 2x+6. The variable is the x.
2x plus 5x simplified is 7x.
