Example 5.2.19. solve the system by substitution. {4x − 3y = 6 15y − 20x = − 30. solution. we need to solve one equation for one variable. we will solve the first equation for x. solve the first equation for x. substitute 3 4y 3 2 for x in the second equation. replace the x with 3 4y 3 2. Example 4.2.1. solve by substitution: solution: step 1: solve for either variable in either equation. if you choose the first equation, you can isolate y in one step. 2x y = 7 2x y− 2x = 7− 2x y = − 2x 7. step 2: substitute the expression − 2x 7 for the y variable in the other equation. figure 4.2.1.
