Question

ihave really bad allergies and icant seem to think straight!

7s+20=40s-13

Answer 1

add the -13 to the 7s+20 and you get 7s+33=40s

minus 7s from 40s and u get 33s=33

divide by 33 s=1

Answer 2

7s + 20 = 40s - 13 (subtract 20 from both sides)

7s + 20 - 20 = 40s - 13 - 20

7s = 40s - 33 (subtract 40s from both sides)

7s - 40s = 40s - 33 - 40s

-33s = -33 (divide both sides by -33)

-33s/-33 = -33/-33

s = 1 <===ANSWER

Answer 3

1) Subtract 7s from both sides, canceling out the 7s on the left side.

7s - 7s + 20 = 40s - 7s - 13

20 = 40 s - 7s - 13

20 = 33s - 13

2) Add 13 to both sides, canceling out the -13 on the right side.

20 + 13 = 33s - 13 + 13

33 = 33s

3) Divide both sides by 33, canceling out the 33 factor of 33s on the right side.

33/33 = 33s/33

1 = 1s

**s = 1**
