Question

solve the equation 3x-⅞=⅔​

Answer 1

Answer:

$3x - \frac{7}{8} = \frac{2}{3} \\ \\ = \frac{24x - 7}{8} = \frac{2}{3} \\ \\ = 3(24x - 7) = 2(8) \\ \\ = 72x - 21 = 16 \\ \\ = 72x = 16 + 21 \\ \\ = 72x = 38 \\ \\ = x = \frac{38}{72} \\ \\ = x = \frac{19}{36}$

Answer 2

Answer

$3x - \frac{7}{8} = \frac{2}{3}$

$3x = \frac{2}{3} + \frac{7}{8}$

$3x = \frac{2 \times 8}{3 \times 8} + \frac{7 \times 3}{8 \times 3}$

$3x = \frac{16 + 21}{24}$

$3x = \frac{37}{24}$

$x = \frac{37}{24} \times 3$

$x = \frac{37}{8}$
