Hey guys my name is Nicholas and im going to show you how to do Two step Algebra Equations. So today I am doing um 3 examples, these questions are from "Why did Gonzo walk around carrying ice cream and a pair of sparrows?"
Questions
12. a/2+8=50
6. x\7-8=-10
11. x\10 -11 = 10
So what you want to do here is to rewrite the question first. second you need to reverse the operations. Then you minus or add on both sides. So to undo the division we need to multiply on both sides as well. Now here is the questions. And also don't forget to do your let statements.
a\2+8=50 Verify
a\2+8-8=50-8 a\2 + 8 = 50 50 = 50
(2)a/2=42(2) 21\2 + 8 = 50
a=21 42 + 8 = 50
x\7 -8= -10 x\7 -8 = -10 -10 = -10
x\7-8+8 = -10 + 8 -14\7 -8 = -10
(7)x\7 = -2 (7) -2 - 8 = -10
x = -14
-x\10 -11 = 10 - x\10 -11 =10 10 = 10
-x\10 -11 + 11 = 10 + 11 -2 10/ 10 - 11 =110
-(10)x\10 = 21(10) 21 - 11 = 10
x=210
So as you can see that I reversed the operations and minus or add both sides so I hope that this can help you a lot im sorry if this didn't help you because honestly I find it hard to explain this. I suck :(.
Let me know if I forgot anything so I'll be more prepared at explaining this in the future.

Here is a video of explaining how to do this. Like A BETTER way than how I say or write it.
