I am not sure how to solve this equation
49x-y=558
Since you have two variables, there is no unique solution.
One solution is
x = 10, y = -68
another
x = 0, y = -558
There is an infinite number of solutions.
To solve the equation 49x - y = 558, you can use the method of isolating one variable and solving for it.
Step 1: Rewrite the equation in terms of one variable. In this case, let's solve for y.
-49x + y = 558
Step 2: Isolate the variable y by moving the -49x term to the right side of the equation.
y = 558 + 49x
Now we have expressed y in terms of x. This means that we can solve for y given any value of x.
If you have additional information or specific values for either x or y, please provide them so that I can further assist you in finding a solution.
