Juilo watched a movie that started at 11: 30 and ended at 2: 12 how long was the

The movie was 2 hours and 42 minutes

Step-by-step explanation:

There are 2 hours from 11:30 to 1:30 and then from 1:30 to 2:12 is 42 minutes

Solution: {x = 2, y = -1/3}

Step-by-step explanation:

On observation, we see that the y-terms are equal and opposite in sign, therefore to solve the system, we add the two equations.

2x-3y = 5 (1)

3x+3y = 5(2)

(1) + (2)

2x - 3y + 3x + 3y = 5+5

5x = 10

x = 2 (3)

Substitute (3) in (2) and solve for x

3x+3y = 5 (2)

3(2) + 3y = 5

3y = 5-6 = -1

y = -1/3  (4)

assemble (3) and (4) to give the answer

Solution: {x = 2, y = -1/3}
