(5t9/ 4 ) = 14
5t9 =14*4 multiply 4 to both sides, and it cancels the 4 on the left side.
5t9=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

Joshua 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?
