Tyler had $65.40 in his checking account. then he wrote checks on the account for $20.38, $11.48, and $19.50. what is the balance of his account now?

money going out (20.38+11.48+19.50) =51.36

balance - out = new balance

65.40-51.36 =

14.04

new balance =  14.04

For the answer to the question above,
x + y = 79
1.65x + 1.36y = $118.17

step 1: x + y = 79
- x - x

y = 79 - x


step 2: 1.65x + 1.36 ( 79 - x) = 118.17
1.65x + 107.44 - 1.36x = 118.17
0.29x + 107.44 = 118.17
- 107.44 - 107.44

0.29x = 10.73

0.29x 0.29x

x = 37


step 3: 37 + y = 79
- 37 - 37

y = 42


final answer: (37, 42)
i hope this
