Answer:
Step-by-step explanation:
5x + 4y = 6
4y = -5x + 6
y = -5/4x + 24......slope here is -5/4 and y int is 24
10x - 2y = 7
-2y = -10x + 7
y = 5x - 7/2.....slope here is 5 and y int is -7/2
if the slopes and the y int's are different, which they are, then there is 1 solution
$126
just used the calculator
500+500 = 1000
100*10 = 1000
10^3 = 1000
10*10*10 = 1000
