Solving systems of equations test pdf

First, solve the first equation for x. Then substitute for x in the second equation. Since the left side does not equal the right, there is no solution to this system of equations. x í y = 1 3x = 3y + 3 62/87,21 x í y = 1 3x = 3y + 3 First, solve the first equation for x to get x = y + 1. Then substitute y + 1 for x in the second equation. Start studying Unit 7 Test: Systems of Equations. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
