Answer: The solution is x = 3/2, y = 8.

Explanation:

These are two simultaneous linear equations and can be solved using substitution or elimination method.By elimination method:

Adding the two equations,

(2x + 1/2y) + (6x - 1/2y) = 7 + 5

8x = 12

x = 3/2

Substituting x = 3/2 in any of the two equations,

2x + 1/2y = 7

2 * (3/2) + 1/2y = 7

3 + 1/2y = 7

1/2y = 4

y = 8The solution is x = 3/2, y = 8.
