Maths entails the usage of our brain juice in solving problems. It is a good platform for stretching our imagination and creativity by using simple concepts learned to handle seemingly complex maths questions.
Let's look at a "complex" simultaneous equations maths problem, and its way of solving (suggested).
Solve for y and x.
How do you go about it?
Look scary, right?
But like what I said, looks can be deceiving. Use the brain to go around the issue!
Tips: The structure of the simultaneous equations looks similar to the conventional type.
Ax + By = nn
Cx + Dy = kk )
So what we have to do can be to simply substitute by m, and by h (or any variable name).
What we thus convert to is:
Will this simultaneous equations be more comfortable to solve?
Hence, a simple twist to the former mathematical questions can result in a totally familiar situations where we have solve many a times.
Thus, the technique and usefulness of substitution cannot be under-estimated.
It can be powerful at times to reveal a beautiful mathematical expression for user to resolve.
