I notice that the ratio of the y-coefficient to the x-coefficient is the same in both

equations. I think that's enough to tell me that their graphs are parallel. So they

don't intersect, and viewed as a pair of simultaneous equations, they have no solution.

How do you find all real solutions to the system of equations 4x 2 plus y 2 equals 100 and 4x 2 minus y 2 equals 62?

Add the two equations together. This will give you a single equation in one variable. Solve this - it should give you two solutions. Then replace the corresponding variable for each of the solutions in any of the original equations.
