0.49s+0.21(s-5)=9.45

0.49 s + 0.21 (s - 5) = 9.45

s = 15

Solution steps

0.49 s + 0.21 (s - 5) = 9.45

Multiply both sides by

100

49 s + 21 (s - 5) = 945

Expand

21 (s - 5) : 21 s - 105

49 s + 21 s - 105 = 945

Add similar elements:

49 s + 21 s = 70 s

70 s - 105 = 945

Move

105

to the right side

70 s = 1050

Divide both sides by

70

s = 15
