Hi my name is Jessica. I love math so I would be happy to help.
Hi! My name is Sarah, and I need help with my math homework, it is about 2 step equations.
Thank you so much!
In 2 step equations you have to get the variable by itself.
Okay! That seems simple, but what is the first step?
What do you do to solve a 2 step equation?
The first step is to do the opposite of the addition or subtraction on both sides.
Yes! then it cancels out the +5 and brings the 21 down to 16. So the updated problem is 2x=16
The Problem is 2x+5=21
.So you would subtract 5 from the +5 and the 21?
The next step in this problem is to do the opposite of the operation which is multiplication, so you would have to divide by 2.
So after we divide by 2 on both sides the updated problem would be x=8 which is the answer.
So the first step to solve a 2 step equation is to do the opposite of the operation during the addition and subtraction.
Then the second step is to do the opposite of the operation during the multiplication and division numbers.
Your welcome! I'm glad you understand.
Thank you so much for teaching me how to solve a 2 step equation! I understand it all now.
