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.
