Question

Solve the following simultaneous equations by using the elimination method:

Answer 1

hey dear.

=) x/2 + y/3 = 6

So talking Lcm and multiply by 6 both sides.

=) 3x + 2y = 36 -----------(1)

=) 2x - y = 3 ---------------(2)

multiply eqn ( 2 ) by 2 and add both eqn

3x + 2y = 36
4x -2y = 6
+____________
7x + 0 = 42

=) x = 42/7 = 6

put value if x in eqn (2)

=) 2(2) - y = 3

=) 4 - y = 3

=) y = 4 - 3 = 1

so value of x = 6 , y = 1
