An algebraic expression doesn't have an equal sign (e.g. 4x+7) whereas an algebraic equation does (e.g. 4x+7=19). 4x=19-7 4x=12 x=12/4 x=3
what is the constant in algebraic experssion 7d+2
It can be: 7-4x as an algebraic expression
4x + 7 = 0 4x = -7 4x/4= -7/4 X = -7/4
It would be: 3(7-d) as an algebraic expression

4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
16c^2-49 -> (4x-7)(4x+7)
If you mean: 4x-14x+7 then the expression can be simplified to 7-10x
