To solve a system of equations by elimination, write the system of equations in standard form: ax + by = c, and multiply one or both of the equations by a constant so that the coefficients of one of the variables are opposite. Then, add or subtract the two equations to eliminate one of the variables.

What is an Equation and an Equation Calculator? An equation is a mathematical form where two expressions are equivalent. It comprises different mathematical techniques, constants, and variables in combination. Finding the value of the unknown variable(s) that renders the equation true is the aim of solving an equation.
