Systems of Equations: E.g. 2x + 3y = 1 x
... Once we found the value of y, we may substitute it into any of the two equations to solve for x: 2x + 3(−1) = 1 2x − 3 = 1 2x = 4 x=2 The solution is (2, −1), notice that the solution is an ordered pair. ...

... Multiplicative inverses are two numbers that when multiplied together equal 1. When you multiply a term with a fractional coefficient by the multiplicative inverse of the fraction, you can isolate the variable on one side of the equation. This is known as multiplying by the reciprocal. When you mult ...
