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! :)
