To simplify the expression ((5x - 7y + 8z) - (-2x + 3y - z)), first distribute the negative sign to the second set of parentheses: (5x - 7y + 8z + 2x - 3y + z). Next, combine like terms: (5x + 2x = 7x), (-7y - 3y = -10y), and (8z + z = 9z). The final simplified expression is (7x - 10y + 9z).
-4(7x-3y-z)-(-6)(9x-z+2)
2x plus 3y is not an equation, it is an expression.
To simplify the expression (2x + 3y - 5x^2 - 10y + 7x^2), first combine like terms. The (x^2) terms combine to (2x^2) (from (-5x^2 + 7x^2)), and the (y) terms combine to (-7y) (from (3y - 10y)). Thus, the equivalent expression is (2x^2 + 2x - 7y).
To find the constant in the expression (8x + 3y - 2x + 6 - 4), first simplify it. Combine like terms: (8x - 2x = 6x) and (3y) remains as is. The constant terms are (6 - 4), which equals (2). Therefore, the constant in the expression is (2).
Actually, 2x + 3y + z is an expression, because it is a mathematical noun.

To find the constant in the expression (8x + 3y - 2x + 6 - 4), first simplify it. Combine like terms: (8x - 2x = 6x) and (3y) remains as is. The constant terms are (6 - 4), which equals (2). Therefore, the constant in the expression is (2).
To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.
