Answer 1

Answer:

Step-by-step explanation:

Given:

2x + 3y = 9

9x + 6y = 7

Solution:

2x + 3y = 9

2x = 9 - 3y

x = (9 - 3y)/2

Substituting x = 9 - 3y/2....we get,

9(9 - 3y/2) + 6y = 7

81 - 27y/2 + 6y = 7

81 - 15y/2 = 7

-15y/2 = -74

y = -74 * -2/15

y = 148/15

Substitute y = 148/15 to find x.
