Question

Solve for s. 1/2 s = 7/2. A 1/7. B 2/7. C 3. D 7.

Answer 1

Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.

$\frac{1}{2} s = \frac{7}{2} \\ \\\frac{(\frac{1}{2}s)}{\frac{1}{2}} = \frac{\frac{7}{2}}{\frac{1}{2}} \\ \\\\s = \frac{\frac{7}{2}}{\frac{1}{2}} \\ \\\\s = \frac{7}{2} * \frac{2}{1} \\ \\\\s = 7$

One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.

Answer 2

The answer is D. 7

Multiply both sides by 2

2*(1/2 s) = 2*(7/2)

s = 7
