Question

Solve the simultaneous equation graphically (2x+3y=8 and 3x+2y=7

Answer 1

Answer:

x = 1

Step-by-step explanation

3 * (Eqn 1) --->    3* (2x + 3y = 8)--->    6x + 9y = 24

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

(6x + 9y = 24  -(6x + 4y = 14) --->5y = 10        

                   

  y = 10/5 = 2

2x + 3(2) = 8

2x + 6 = 8        

2x = 2      

 x = 1
