Sponsors:

5s + 10 = 200

You need to get rid of 10 first, you do this by subtracting it by 10, you also subtract 10 to 200

5s = 190

Now you need to get rid of 5 that is attached to the variable, you must divide 5 since it is multiplying, also dividing 5 to 190

s = 38

So it would be 38 sponsors

Comic books:

4c + 6 ≤ 20

Take away 6 by subtracting, also subtracting 6 to 20

4c ≤ 14

You then have to divide 4 to the variable, also dividing 4 to 14

c ≤ 3.5

Now since you can’t get half of a comic book, the greatest amount of comic books he can buy is 3.

3 comic books

Value of x:

3x + 1 = 10

Take away 1 by subtracting 1, also subtracting 1 to 10

3x = 9

Divide 3 to the variable, dividing 3 to 9 as well

x = 3

Value of y:

4y + 6 ≥ 18

Subtract 6 to 6 and 18

4y ≥ 12

Divide 4 to both sides

y ≥ 3 or y is greater than or equal to 3 (in case you can’t see the symbol)

Hope this helps! :)
