Question

Find the solution sets of each equation if the replacement sets are A=(4,5,6,7,8) and B= (9,10,11,12,13)
Problem is 5a-9=26

Answer 1

I've never seen the term replacement sets, can you explain that?

Answer 2

This is my first time seeing this also.. I Don't understand what they mean by this, I mean wouldn't you add 9 to each area?

Answer 3

yea, so to solve for a that's the first step.

Answer 4

Now what about b? lol

Answer 5

huh?

Answer 6

I was just solving 5a-9=26

Answer 7

Sorrry, I'm like so lost, so the answer would be a=7, right and there's nothing more to that?

Answer 8

yea, but I don't know what to do with those replacement sets

Answer 9

i've never heard that before,

Answer 10

Let me try to see if I can find anything

Answer 11

@nincompoop have you heard of replacement sets?

Answer 12

I'm pretty sure it just means like that a has to be one of those answers, or b has to be one of those said?

Answer 13

I was thinking maybe it was a lazy way to write like 5 questions in one

Answer 14

Okay, so this one, I always get confused with the negatives... Problem is 7a+21= 56

Answer 15

Still be a postive right cause the 56 is bigger whensolveD?

Answer 16

so you replace the coefficient with set A and the number with set B

Answer 17

uhm so that one, how do you 'undo' addition?

Answer 18

subtra

Answer 19

7a=35

Answer 20

a=5 of course lol

Answer 21

yup

Answer 22

medal pwease?
