How Do You Find The Substitution? Solve one equation for one of the variables. Substitute (plug-in) this expression into the other equation and solve. Resubstitute the value into the original equation to find the corresponding variable. How do you solve by substitution step by step? Step One→ Solve one equation for either x or y.
How Do You Solve Two Equations Using Substitution? Select one equation and solve it for one of its variables. In the other equation, substitute for the variable just solved. Solve the new equation. Substitute the value found into any equation involving both variables and solve for the other variable. How do you solve an equation
How Do You Solve Substitution Problems? The method of solving “by substitution” works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, “substituting” for the chosen variable and solving for the other. Then you back-solve for
