Answer 2

To solve these equations, you need to isolate the variables x and y. Let's solve each equation step by step:

1. 14x + 27x = 656

Combine like terms on the left side:

41x = 656

Now, isolate x by dividing both sides by 41:

x = 656 / 41 x = 16

So, the solution to the first equation is x = 16.

2. 81y - 38y = 645

Combine like terms on the left side:

43y = 645

Now, isolate y by dividing both sides by 43:

y = 645 / 43 y = 15

So, the solution to the second equation is y = 15.

Therefore, the solution to the system of equations is x = 16 and y = 15.
