Answer:
x = 12
y = 14
Explanation:
5x + 4y = 116
5 x 12 = 60
4 x 14 = 56
60 + 56 = 116
10x + 6y = 204
10 x 12 = 120
6 x 14 = 84
120 + 84 = 204
-------------------------------------------
Here's how I found x and y:
10x + 6y = 204 can be divided by 2
5x + 3y = 102
Then I took 116 and subtracted 116 given the difference
in y.
116 - 102 = 14
So y = 14 and then I sovled for x:
5x + 56 = 116
116 - 56 = 60
60/5 = 12
10x + 84 = 204
204 - 84 = 120
120/10 = 12
