Do have trouble finding t?

yeah all i need to find is t. it is really confusing me. can you please help me find what t is? if so thanks a lot

• pre- algebra -

(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

thanks a million!!

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?
