10x + 25y = 11,700
2x + 3 = y
----------------------------------------------------------------------------------------------
Elimination method:
Isolate the number from the variables:
10x + 25y = 11,700
2x - y = -3
Multiply the second equation by 5 to eliminate x:
10x + 25y = 11,700
10x - 5y = -3
Subtract:
30x = 11,703
Divide by 30:
x = 390.1
Plug x back in.
3901 + 25y = 11,700
Isolate y:
25y = 7802
y = 312.08
