The two equations you have provided represent two straight lines in a Cartesian coordinate system. In order to find the point at which these two lines intersect, you need to find the values of x and y that satisfy both equations simultaneously.
Setting the right-hand sides of both equations equal to each other, we get:
2x + 56 = 9x
Solving for x, we can subtract 2x from both sides:
56 = 7x
Finally, dividing both sides by 7:
x = 8
Now that we have found the value of x, we can use either of the two equations to find the value of y:
y = 2x + 56
y = 2 * 8 + 56
y = 112
So, the solution to the system of equations is (x, y) = (8, 112).
