Let x = # of apples and y = # of oranges.

x + y = 163

x = 163 - y

.5x + .8y = 110

Substitute 163-y for x in last equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.

let the number of apples be x

let the number of oranges be y

x+y = 163 ---> y = 163-x

.5x + .8y = 110

5x + 8y = 1100

use substitution

5x + 8(163-x) = 1100

5x + 1304 - 8x = 1100

-3x = -204

x = 68

he has 68 apples and 95 oranges at first
