Answer 1

add 1 to both sides to get 4/3s=1 1/3
divide 4/3 from both sides
s=?

Answer 2

wouldn't i divide 3/4 instead of 4/3

Answer 3

no when you go to divide 4/3 from the other side you will multiply 3/4 to 1 1/3

Answer 4

so it S = 1?

Answer 5

that's what I got!

Answer 6

Add one to both sides, then
Multiply both sides by 3/4 to isolate s

Answer 7

\[\frac{4}{3}s - 1 = \frac{1}{3}\]
\[\frac{4}{3}s = \frac{1}{3} + 1\]
\[\frac{4}{3}s = \frac{1}{3} + \frac{3}{3}\]
\[\frac{4}{3}s = \frac{4}{3} \]

Multiply both sides by 3/4 to isolate s
\[\frac{3}{4} \times \frac{4}{3}s = \frac{4}{3} \times \frac{3}{4}\]
\(s = 1\)

Answer 8

Forget about trying to divide both sides by something in this case. You'll only confuse yourself. Just multiply both sides by the reciprocal when trying trying to isolate a variable being multiplied by a fraction.
