-y+9z-16y-25z= -y-19y+9z-25z= -20y-16z There you go, are you happy. p.s it was easy (im 13yr)
y-5x
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
Sure thing, honey. To simplify that expression, you just distribute the 8 to both terms inside the parentheses. So, you get 8y + 8z. That's all there is to it, darling.
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
5y - 4 + 9y - 1y + 15= 5y + 9y - 1y + 15 - 4= (5 + 9 - 1)y + (15 - 4)= 13y + 9

To simplify the expression "x + x + x + x + y + y + y + x," you can first combine like terms. Group the x terms together and the y terms together. This gives you 4x + 3y. So, the simplified form of the expression is 4x + 3y.
4a2 + 4ab - y2 + b2 You cannot simplify this expression because it does not contain like terms, but you can factor it such as: 4a2 + 4ab - y2 + b2 = (4a2 + 4ab + b2) - y2 = (2a + b)2 - y2 = [(2a + b) - y][(2a + b) + y]
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.
