By7.3 ET: Solve. Using back substitution (1, -1, 2). Use these two equations to create an equation with only x & y. Solve: Strategy 1 st create two equations w/the same two unknowns. Use these two equations to create an equation with only x & y. (1, ½, -3). Let’s get rid or y.

BySolving Equations with Variables on Both Sides . Sol A.4 Chapter Lesson 2-4. Step 1 – Use the Distributive Property to remove any grouping symbols. Use properties of equality to clear decimals and fractions. Step 2 – Combine like terms on each side of the equation.

Byy = 3x + 4. 2x + y = -1. 2x + y = -1. (-1, 1) is where the two lines intersect. This point is a point on both lines. Therefore, if we substitute -1 in for x and 1 in for y, we should get a true statement, for both equations. y = 3x + 4 1 = 3 (-1) + 4 1 = -3 + 4 = 1
