What is the solution to this system of equations? x+2y=4 2x-2y=5 a. (3, -5.5) b. (3, 0.5) c. no solution d. indefinitely many solutions

b.  (3, 0.5).

Step-by-step explanation:

x + 2y = 4

2x - 2y = 5

Adding the 2 equations eliminates the y:

3x = 9

x = 3

Substitute fro x in the first equation:

3 + 2y = 4

2y = 1

y = 0.5.

x = 12

y = 1
