For example lets solve the following numerical expressions. Equations such as x 3 7 are first-degree equations since the variable has an exponent of 1. This equation has the solution x4 read how to solve equations.
Two equations are equivalent if they have the same solution.
What is a Formula. Equivalent equations are two equations that have the same solution. Equations such as x 3 7 are first-degree equations since the variable has an exponent of 1. These fractions represent the same proportion of the whole.
