Question 68570
First, write the equation in algebra: Let n = the required number.
{{{10+6n = n-5}}} Simplify and solve for n. Subtract n from both sides.
{{{10+5n = -5}}} Now subtract 10 from both sides.
{{{5n = -15}}} Finally, divide both sides by 5.
{{{n = -3}}}

Check:
Substitute n = -3 into the original equation.
{{{10 + 6(-3) = (-3) - 5}}} Simplify.
{{{10 + (-18) = -8}}}
{{{-8 = -8}}} It checks!
