Possibly as a result, there is no equation in the question, only an expression. Furthermore, a linear equation can have only one solution.
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
The number of solutions an equation has depends on the nature of the equation. A linear equation typically has one solution, a quadratic equation can have two solutions, and a cubic equation can have three solutions. However, equations can also have no solution or an infinite number of solutions depending on the specific values and relationships within the equation. It is important to analyze the equation and its characteristics to determine the number of solutions accurately.
The discriminant is 36 which means the quadratic equation has two solutions which are 5 and -1
Assuming you mean:(4x+36)(8x-40) = 0 then you can use the property that a product can only be zero if one of its factors is zero. In other words, you can change this to: 4x + 36 = 0 OR 8x - 40 = 0 Solve each of the individual solutions; their solutions are also solutions to the original equation.
We start with 4x + 8 = 5x -5. Subtract 4x from both sides of the equation, which gives us 8 = x - 5. Add 5 to both sides of the equation, this gives us 13 = x. Problem solved.
