Question

solve the following pairs of equations by reducing them to a pair of linear equations:
1/2x + 1/3y = 12
1/3x + 1/2y = 13/6

Answer 1

Answer:

x=38

y=-21

Step-by-step explanation:

1/2x+1/3y=12

=)3x+2y=82

=)6x+4y=144........1

and

1/3x+1/2y=13/6

=)2x+3y=13

=)6x+9y=39........2

On substracting 2 from 1, we get

5y=-105

=)y=-21

Substituting the value of y in 1, we get

3x+42=72

=)x=38
