For the equation:

You want to multiply 4 into the first parenthesis as follows:

Now combine like terms, add the t's and the numbers from left to right, and remember to keep the negative sign of the larger number.

For the next problem:

Here, you want to multiply 5 into the parenthesis:

Next is to combine like terms on the left side of the equation:

Now, you want to get z by itself to solve for it, so subtract 4z to the left side of the equation.

For the last problem:

You would multiply 4 into the first parenthesis, and multiply 2 in the second parenthesis:

Next, you want to get x by itself, you can subtract 14x from the right side of the left side of the equation.

Now, you would subtract the 12 (next to 6x) to the other side of the equation to get x by itself.

In this case, when you divide by 6 to get x by itself, you're left with
This just equals 0.
