Say you have a pair of equations like a+b=1 and 2a+3b=5. To solve using substitution you would set one equation against one variable (say a=1-b) then plug that into the other (2(1-b)+3b=5), then solve for the one variable you have there and then plug that result into the other equation (in this case b=3 and a=-2).

How do you solve mathematical induction problems?
Assume something (e.g. equations) using k then prove k+1 using k.
Use the guess-and-check method to solve the equation?
OK for very simple equations but not much good otherwise.
Why do you use the order of operations?
We use the order of operations as a method of solving mathematical equations containing three or more operation symbols. The order of operations help us to solve certain segments of the equation before adding it all together to find out what the final answer is.
How do you solve trigonometric equations?
The answer depends on the nature of the equations.
Use the substitution method to solve the system of equations Choose the correct ordered pair?
