To remove y, multiply the first equation by 2 and then add the two equations together. 1 X 2 => 4x + 2y = 12 3 2 + 1 => 7x = 14 x = 2 Sub in 1 4 + y = 6 y = 2 The solutions are x = 2 and y = 2. E.g.3. 2x + 3y = 1 1 3x - 2y = 8 2 In this case, to eliminate y, the first equation must be multiplied by 2 and the second equation must be multiplied by 3.

The equation. 16 x − 5 x = 32 − 10 {\displaystyle 16x-5x=32-10} does have all the varying terms on one side (LHS), while all the constant terms are on the other side (RHS).The y-coordinate can be found by placing the x-coordinate, 1.6, into either of the equations for the lines and solving for y. We will first use the equation for Line 1: y = 2x + 3. y =2(1.6) + 3. y = 3.2 + 3. y = 6.2. Therefore, the y-coordinate is 6.2.
