There are no solutions, but try to figure out why.
OpenStudy (mathstudent55):
Combine like terms on the left side. What do you get?
OpenStudy (mathstudent55):
\(4x − 8 − 4x = 9\) \(4x - 4x - 8 = 9\) What is 4x - 4x ?
OpenStudy (anonymous):
so zero?
OpenStudy (mathstudent55):
Yes. 4x - 4x is zero, so the equation simplifies to: -8 = 9 Since that is a false statement, that means there are no solutions tot eh equation.
