-3(x-5)-2x=-10

Distribute.

-3x+15-2x=-10

Combine like terms.

-5x+15=-10

Subtract 15 on both sides.

-5x=-25

Divide by -5 on both sides.

x=5

I hope this helps!

1 cm on a map is 50 km cm on the actual

using proportion

$\frac{1}{50}\frac{cm}{km}=\frac{x}{480}\frac{cm}{km}\\ \\x=480/50\\ \\x=9.6\ cm$
