Question

Solve for s.

2s − 13 = 5

s =

Answer 1

2s-13= 5

2s-13+13= 5+13

moving -13 to the other side

2s= 5+13

2s= 18

divide both sides by 2

2s/2= 18/2

Cross out 2 and 2 , divide by 2 and then becomes 1*1*s=s

s= 18/2

Answer: s= 9

Answer 2

18÷2=9

Explanation:

2s-13=5

2s=5+13

2s= 18

answer is 9
