Hi. Welcome to my scribe post about 2 step Algebra. In our previous math class Mr. Harbeck taught us how to solve 2 step problems.
The two problems I will be solving are:
Here is how you solve it:
First Step: Do Combining Like Terms by adding 3x and 2x to make it into 5x
Second Step: Re-write the problem so that the coefficient, variable, and constant goes first and the answer is last. Make sure to take away the -7 out by adding +7 which will give you 9+7=16
Third Step: After that you get 5x=16. To isolate the variable, you will need to divide 5x and 16 by 7
Here is how you solve the second question:
20n=-5 ÷ 5
20 20 ÷ 5
First Step: Combining Like Terms. Add -n (-1n) and 21n
Second Step: Re-write the question,make sure to take away the +5 by adding -5 to it.
Third Step: When you get 20n=-5, you divide that by 5/5.
