Question

How do you solve$3$ equations with $3$ variables $?$

Answer 1

Solving $3$ equations with $3$ variables:

We can solve the system of equations with three variables by three different methods:

1. Elimination method
2. Substitution method
3. Cross multiplication method

Elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods.

Substitution method involves substituting the value of any one of the variables from one equation into the other equation.

In cross multiplication method we multiply the numerator of one fraction to the denominator of other and denominator of the first term to the numerator of another term.

Hence, we can simplify three equations with three variables by above three methods.
