Question

Check which of the following are solutions of the equation 2x-3y=1
(2,1) (1,2) (3,0)​

Answer 1

2x - 3y = 1

2(2) - 3(1) = 4 - 3 = 1

Hence ( 2, 1 ) is the solution

Answer 2

Answer:

Solve the following simultaneous equations graphically.

i. 2x + 3y = 12 ; x – y = 1

ii. x – 3y = 1 ; 3x – 2y + 4 = 0

iii. 5x – 6y + 30 = 0; 5x + 4y – 20 =0
