WebOct 6, 2024 · 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 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.
