5x+4=9 its an expression which is greater than 1 you can do almost any expression but it has to be more than one.
Hope this helps :D
Please don't post masses of questions all at once. 1-2 problems per post would be more realistic and fairer to others who need help.
Regarding <span>x-2/5 = 1/5
We are to solve for x. To do this, let's remove the fractions by mult. all 3 terms by 5. Then 5x - 2 = 1, or 5x = 3.
Dividing both sides by x, we get x = 3/5 (answer). Check this by subst. 3/5 into the original equation.</span>
Lets say a number is x
The sum of 5 and three times a number
The sum of 5 and 3 times x
The sum of 5 and 3x (sum means to add)
3x + 5
answer
The answer in simplest radical form is:
