Hi Julian.Ignacio,

Let me get you started with the first two, and then you show us how you might start the other two.

1.

Step 1: Subtract 6x from both sides of the equation to get the variable to one side of the equation.

Step 2: Add 4 to both sides to isolate the variable (get it to one side by itself).

Step 3: Finally, divide both sides by 86 and simplify.

2.

Step 1: Use the distributive property to simplify the equation.

Step 2: Combine like terms.

Step 3: Add 21 to each side.

Step 4: Add 3t to both sides.

Step 5: Finally, divide both sides by 6.

Good luck with the other two. Let us know if you have problems. Show us some of your work. - September 21st 2009, 09:59 AMJulian.Ignacio
