Answer: 3/4 of an hour left.
Step-by-step explanation:
Step 1: 2 hours = 4/4 +4/4
Step 2: 4/4 - 2/4 = 2/4
Step 3: 4/4 - 3/4 = 1/4
Step 4: 2/4 + 1/4= 3/4
3x + 2y = 7
y = x - 4
3x + 2(x - 4) = 7
3x + 2x - 8 = 7
5x = 7 + 8
5x = 15
x = 15/5
x = 3
y = x - 4
y = (3) - 4
y = -1
the solution to the set is (3, -1)
