4x + 7 = 0
4x = -7
4x/4= -7/4
X = -7/4

In the expression (7 + 2x), the constant is (7). A constant is a term that does not change and does not contain any variables, while (2x) is a term that depends on the variable (x). Therefore, (7) remains the same regardless of the value of (x).
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
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
4x - 3 - 4 is one possible answer.
The given expression can be simplified to: 4x -16
It can be: 7-4x as an algebraic expression
