If you would like to solve the following equations for x and y, you can calculate this using the following steps:
x + y = 10
2 * x + 4 * y = 36
_______________
x = 10 - y
2 * (10 - y) + 4 * y = 36
2 * 10 - 2 * y + 4 * y = 36
20 + 2 * y = 36
2 * y = 36 - 20
2 * y = 16 /2
y = 16/2
y = 8
x = 10 - y = 10 - 8 = 2
Result: x equals to 2 and y equals to 8.
