25:(x+2/3)=6

Answer 1

$25 \div (x + \frac{2}{3} ) = 6 \\ 25 \div \frac{3x + 2}{3} = 6 \\ 25 \times \frac{3}{3x + 2} = 6 \\ \frac{75}{3x + 2} = 6 \\ 75 = 6(3x + 2) \\ 75 = 18x + 12 \\ - 18x = 12 - 75 \\ - 18x = - 63 \\ x = \frac{7}{2} = 3 \frac{1}{2}$

Answer 2

$25:(x+\frac{2}{3})=6\\x+\frac{2}{3}=25:6\\x+\frac{2}{3}=4\frac{1}{6}\\x=4\frac{1}{6}-\frac{2}{3}\\x=3\frac{7}{6}-\frac{4}{6}\\x=3\frac{3}{6}\\x=3\frac{1}{2}$
