Question

5 x by 4 minus 3 by 8 is equal to 9 by 5 + 8 by 5

Answer 1

Heya!

$\frac{5x}{4} - \frac{3}{8} = \frac{9}{5} + \frac{8}{5} \\ \frac{5x}{4} - \frac{3}{8} = \frac{9 + 8}{5} \\ \frac{5x }{4} - \frac{3}{8} = \frac{17}{5} \\ \frac{10x - 3}{8} = \frac{17}{5} \\ 10x - 3 = \frac{17}{5} \times 8 \\ 5 \times (10x - 3) = 17 \times 8 \\ 50x - 15 = 136 \\ 50x = 136 + 15 \\ 50x = 151 \\ x = \frac{151}{50} \\ x = 3.02$
