Question

3/8x-1/5x=10=3/10x

Answer 1

too many equal signs

Answer 2

is it
\[\frac{3}{x}x-\frac{1}{5}x=10+\frac{3}{10}x\]?

Answer 3

oh sorry, it's 3/8x-1/5x-10=3/10x

Answer 4

ah
best bet is to clear fractions by multiplying both sides by 40

Answer 5

\[40(\frac{3}{8}x-\frac{1}{5}x-10)=\frac{3}{10}x\times 40\]
\[15x-8x-400=12x\]
\[7x-400=12x\]
\[-400=5x\]
\[\frac{-400}{5}=x\]
\[x=-80\]
