Solve for x. −4/5x+3/10<8/10

Genrish500 [490]

Answer:

for (−4/5)x + 3/10 < 8/10: solution is x > -5/8

for −4/(5x) + 3/10 < 8/10: solution is x > -8/5

Step-by-step explanation:

I'm not exactly sure if you mean -4 divided by 5x or (-4/5)x, so I've done both! :)

$-\frac{4}{5}x+ \frac{3}{10} < \frac{8}{10}$

subtract 3/10 from both sides: $-\frac{4}{5}x < \frac{5}{10}$

Divide both sides by 4/5: $-x < \frac{5}{8}$

Divide both sides by -1 (reverse sign): $x > -\frac{5}{8}$

$-\frac{4}{5x}+ \frac{3}{10} < \frac{8}{10}$

subtract 3/10 from both sides: $-\frac{4}{5x} < \frac{5}{10}$

Multiply both sides by 5x: $-4 < \frac{5}{2}x$

Divide both sides by 5/2: $x>- \frac{8}{5}$
