xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
You cannot. What you have in the question is an expression. An expression cannot be proven. You need an equation (or inequality).
The expression written in the question is the rational expression.
x does not equal -1, because if x is minus 1, x plus 1 is zero and division by zero is not defined.
The expression is 5d+2c and the unknown variables are d and c
It is an expression that can be simplified to: 12-5d
Do you mean: 11d +1 = 5d+49? If so: 11d+1 = 5d+49 11d-5d = 49-1 6d = 48 d = 8
To simplify the expression 5d + 2(3d), you first distribute the 2 to the terms inside the parentheses, which gives you 5d + 6d. Combining like terms, you add the coefficients of the d-terms together to get 11d. Therefore, the simplified expression is 11d.

4e + 3d + 5e - 5d = 9e - 2d
b + 1 is b plus 1 as an algebraic expression.

5d-1=-11 5d=-11 + 1 5d=-10 d= -10/5 d=-2
8d = 5d+18 8d-5d = 18 3d = 18 d = 6
5de
5d + 19 = 79 ````-19` -19 5d = 60 `/5` /5 d=12
