Two-thirds ([tex] \frac{2}{3} [/tex]) a number (n) plus (+) 4 equals (=) 7.


[tex] \frac{2}{3} [/tex]n + 4 = 7   Subtract 4 from both sides
[tex] \frac{2}{3} [/tex]n = 3   Multiply both sides by [tex] \frac{3}{2} [/tex] to cancel out the fraction ( [tex] \frac{2}{3} x \frac{3}{2} = 1 [/tex]) (3 x [tex] \frac{3}{2} [/tex] = [tex] \frac{3 x 3}{2} [/tex] = [tex] \frac{9}{2} [/tex] = [tex]4 \frac{1}{2} [/tex]
n = 4 [tex] \frac{1}{2} [/tex]
