*Learn easy with Example*

Equation 1: 2x + 3y = 8

Equation 2: 3x + 2y = 7

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. An easy choice is to multiply Equation 1 by 3, the coefficient of x in Equation 2, and multiply Equation 2 by 2, the x coefficient in Equation 1:

  • (Eqn 1),

(2x + 3y = 8) ---> 6x + 9y = 24

  • (Eqn 2),

(3x + 2y = 7) ---> 6x + 4y = 14

Both equations now have the same leading coefficient = 6

Step 2: Subtract the second equation from the first.

-(6x + 9y = 24

-(6x + 4y = 14)

5y = 10

Step 3: Solve this new equation for y.

y = 10/5 = 2

Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x. We'll use Equation 1.

2x + 3(2) = 8

2x + 6 = 8 Subtract 6 from both sides

2x = 2 Divide both sides by 2

x = 1

Solution:

x = 1, y = 2 or (1,2)
