The sum of two numbers is 80 If four times the smaller number is subtracted from the larger number, the result is 10. Find the t
timama [110]
This can be solved using a system of equations. 
\left \{ {{x+y=80} \atop {x-4y=10} \right. 

Subtract y from both sides.
x=80-y
Substitute:
80-y-4y=80-5y=10
Subtract 80 from both sides:
5y=70
Divide both sides by 5:
y= \frac{70}{5} =14
Substitute.
x=80-14=66
