X+x+y=6 y-x=7

To solve this system of equations, you can use the method of substitution or elimination. Let's solve it using substitution:

From the second equation, we can express y in terms of x: y = x + 7

Now substitute this value of y into the first equation: x + x + (x + 7) = 6

Simplify the equation: 3x + 7 = 6

Subtract 7 from both sides: 3x = -1

Divide both sides by 3: x = -1/3

Now substitute the value of x back into the equation y = x + 7: y = (-1/3) + 7 y = 20/3

Therefore, the solution to the system of equations is x = -1/3 and y = 20/3.
