WebSolving systems of equations with the substitution method. We can follow the following steps to solve the system by substitution: Step 1: Simplify the equations: This includes removing parentheses, combining like terms, and removing fractions. Step 2: Solve an equation for one variable. It does not matter which equation or variable we choose. WebMar 2, 2024 · If one of the equations looks more complicated than the other, just plug it into the easier equation. Plug x = 3 into the equation x - 6y = 4 to solve for y. 3 - 6y = 4. -6y = 1. Divide -6y and 1 by -6 to get y = -1/6. You have solved the system of equations by addition. (x, y) = (3, -1/6) 5. Check your answer. california zephyr youtube
