Question

A - 15 = 22

———

83 = y - 17

could someone please give me the step-by-step answer for these?
I’m really confused

Answer 1

Answer:
1. a = 37
2. 100 = y

Step-by-step explanation:

First problem:

First: You have to get the variable (a) alone, so you must get rid of the “- 15” and in order to do this you have to do the opposite of subtraction, which is addition. You have to add 15 to 22 as well since both sides of the equal sign have to do the same thing.

a - 15 = 22
+ 15 + 15

Second: There is nothing else to do, the answer is a = 37

a = 37

Second problem:

First: Just like the first problem you must get t the variable (y) alone. Since 17 is being subtracted from the variable you must add 17 to “- 17” and just like last time you must do the same to the other side of the equal sign! So you’ll be adding 17 to 83

83 = y - 17
+ 17 + 17

Second: There is nothing else to do, you’re left with 100 = y

100 = y

Answer 2

a = 37 y = 100

Step-by-step explanation:

Think of the inverse operation of addition which is subtraction. Then you can guess and check and see what fits where. The letters are just placeholders so I took the given number and added it to the answer to get the answers for the blanks.
