y-5x
It is the same as 8y+8z
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
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
y-5x
It is the same as 8y+8z
Y plus Y = 2Y simplified

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]

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
3y+2z
The answer is 5x+3y. (5 xs and 3 ys)
y-3x+2 is an expression, not an equation. An expression cannot be solved.
