Answer:
There are 23 $10 notes and 11 $5 notes
Step-by-step explanation:
x= Number of $10 notes
y= Number of $5 notes
1 x + 1 y = 34 .............1
Total value
10 x + 5 y = 285 .............2
Eliminate y
multiply (1)by -5
Multiply (2) by 1
-5 x -5 y = -170
10 x + 5 y = 285
Add the two equations
5 x = 115
/ 5
x = 23
plug value of x in (1)
1 x + 1 y = 34
23 + y = 34
y = 34-23
y = 11
y = 11
x= 23 Number of $10 notes
y= 11 Number of $5 notes
