**Joshua**, Sunday, February 17, 2008 at 3:07pm(5t-9/ 4 ) = 14

5t-9 =14*4 multiply 4 to both sides, and it cancels the 4 on the left side.

5t-9=56 add 9 to both sides, and it cancels on the left side.

5t=56+9

5t=65 divide by 5 on both sides

t= 13

**Guido**, Sunday, February 17, 2008 at 6:52pmJoshua did a great job!

I just want to say that to solve for a variable (any variable) means to isolate the variable on one side of the equation.

Do you see, as Joshua said, that

t = 13?

Do you see that the letter or variable t has been isolated on one side of the equation?

That means Joshua solved the equation for t.

To find out if Joshua is correct (and he is), replace t with 13 in the original equation given and simplify.

If you get the SAME answer on both sides of the equation, then you will know FOR SURE that t = 13.

Got it?
