Julius sold 5x as many computers as Sam sold last year. In total they sold 78 computers. How many computers did Julius sell.
**Solve each problem by WRIING and solving the equation.

I will assume that 5x means "5 times "
Sam  x
Julius  5x
x + 5x = 78
6x = 78
x = 13
julius sold 5(13) or 65 computers
what does WRIING stand for ?
