Help answer this question below.
5x + 9 = 4x
-5x from both sides
9 = -x
Multiply -1 on both sides
x = -9
5x + 9 = 4x
9 = -x
x = -9
Easy peasy algebra! :D
The correct answer to your question is that 5x + 9 = 4x is an algebraic expression. If you wanted the value of x, the question should be "In the following expression, what is the value of x?" or simply "solve for x"
