Two-thirds (\(\frac{2}{3}\)) a number (n) plus (+) 4 equals (=) 7.
\(\frac{2}{3}\)n + 4 = 7 Subtract 4 from both sides
\(\frac{2}{3}\)n = 3 Multiply both sides by \(\frac{3}{2}\) to cancel out the fraction ( \(\frac{2}{3} x \frac{3}{2} = 1\)) (3 x \(\frac{3}{2}\) = \(\frac{3 x 3}{2}\) = \(\frac{9}{2}\) = \(4 \frac{1}{2}\)
n = 4 \(\frac{1}{2}\)
