Answer:4/5 and y = 9/5.

Step-by-step explanation:We can start by substituting the second equation into the first equation, replacing y with 1/2x+8:

3x + 4(1/2x+8) = 36

Simplifying, we get:

3x + 2x + 32 = 36

Combining like terms, we get:

5x + 32 = 36

Subtracting 32 from both sides, we get:

5x = 4

Dividing both sides by 5, we get:

x = 4/5

Now that we have found x, we can substitute it back into the second equation to find y:

y = 1/2x + 8 = 1/2(4/5) + 8 = 9/5

Therefore, the solution to the system of equations is x = 4/5 and y = 9/5.
