9x%2B5=30 Start with the given equation



9x=30-5Subtract 5 from both sides


9x=25 Combine like terms on the right side


x=%2825%29%2F%289%29 Divide both sides by 9 to isolate x



x=25%2F9 Reduce

--------------------------------------------------------------
Answer:
So our answer is x=25%2F9 (which is approximately x=2.77777777777778 in decimal form)


So this means that 3 is not a solution of the equation 9x%2B5=30
