10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
6x-2y
To solve this, you would normally set up a systems of equations 10x + 2y = 10 10x + 2y = 11 However, it clearly makes no sense and has no answer. To prove this mathematically, subtact the two equations. 10x - 10x = 0 2y - 2y = 0 10-11 = -1 Therefore, it is basically saying that 0 + 0 = -1 Obviously, that is incorrect, so this question has no solutions.

the answer to this problem is -2x^2y^2
10x + 41y142x + 2y
To simplify the expression 13x + 2y - 10x - 7y, you first combine like terms. Group the x terms together and the y terms together: (13x - 10x) + (2y - 7y). This simplifies to 3x - 5y. Therefore, the simplified expression is 3x - 5y.
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z

10x - 5y + 2x - 3y = 12x - 8y
the answer to this problem is -2x^2y^2
8y-7x
3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
To simplify Y plus Y, you can combine the like terms. In this case, both Y terms are like terms because they have the same variable. When you add them together, you get 2Y. Therefore, Y plus Y simplifies to 2Y.
