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.
It is: 2d+9
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
ac-5ad-5bc+25bd a(c-5d)-5b(c-5d) (a-5b)(c-5d) FOIL First (a*c=ac) Outside (a*-5d=-5ad) Inside (-5b*c=-5bc) Last (-5b*-5d=25bd) ac-5ad-5bc+25bd
4e + 3d + 5e - 5d = 9e - 2d
b + 1 is b plus 1 as an algebraic expression.
Need your help for answer
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
