Answer 2

It seems like you've provided a system of linear equations:

1. x + y = 42
2. 7x + 2y = 2

To solve this system of equations, we can use various methods. One common approach is the substitution method:

From equation 1, we can solve for x: x = 42 - y

Now, substitute the expression for x into equation 2:

7(42 - y) + 2y = 2

Distribute the 7: 294 - 7y + 2y = 2

Combine the y terms: 294 - 5y = 2

Subtract 294 from both sides: -5y = -292

Divide by -5: y = 58

Now that we have the value of y, we can substitute it back into the expression for x:

x = 42 - y x = 42 - 58 x = -16

So, the solution to the system of equations is x = -16 and y = 58.
