>>1550508This is what I'd do:
OK we have two equations. And they both have to be true. What you usually do there is add the left hand sides of both equations, put that on the left of a new equation, then add the right hand side of both equations, and put that on the right of a new equation. For example:
if these are the equations we're given
2x = y
2x + y = 30
then i'd do like this
2x + 2x + y = y + 30
4x + y = y + 30
4x = 30
x = 7.5
So it should be the same thing here.
(add the left hand sides and right hand sides)
d^3 - h + h^3 + d = 26 + 4
Now here is where I fail because I don't know how to solve such equations and can't think of anything to do.
