2: A two step equation is a problem that gives you the answer, and uses a variable and numbers to find out how to get the answer that you already have. It uses two operations. To find the answer you must use the inverse operation of the constant to cancel it out, then use the inverse of the constant on the answer.Do the same with the co-efficient. You right down what the variable equals, then you must check your answer, here's how | Concept
3: You plug in the number that the variable equals, into the equation in place of the variable then solve the equation. If it works, then you have done it right.
4: How to solve a two step equation with adding & multiplying | To solve this take the constant and use the inverse operation and use it on itself to cancel it out and use it on the other side of the equal sign. Use the co-effecnt and do the same thing. Now you have your answer. Now check. 3n+6=12 5n+20=35 3(2)+6=12 5(3)+20=35 6+6=12 15+20=35 12=12 35=35
5: Adding & Multiplying Two-step equation | 3n + 6 = 12 -6 -6 3n = 6 /3 =/3 n = 2 | 5n + 20 = 35 -20 -20 5n = 15 /5 = /5 n = 3
6: Subtraction & Division | 2 step equations | Examples 1.) _V_ - 8 = -6 2.) _V_ -5= -6 -6 8 _V_= 2 _V_ = -1 -6 8 V=-12 V=-8 _-12_ -8=-6 _-8_ -5 = -6 -6 8 2-8=6 -1-5 =6 6=6 -6=-6
7: How to Solve a two step equation with Subtraction & Division First you cancel out the constant. You do the opposite operation to get rid of it. Which in this case is minus eight so you add eight to both sides. So then you have the variable plus whatever is attached. So then you do the opposite operation to get rid of it again.Which would be multiplying -6 to both sides. | To end you should have the variable and what it equals and don't forget to check.
8: The Check
9: The Check | How to do the check the right way! First: Rewrite the original problem. Second: Go through the problem using the order of operations. Be sure you are actually doing the math Third: Warning this step is very important! Make sure the numbers match up and you are not just writing the answer to make it look like you did the work!
