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).
