Answer:
y = -3
Step-by-step explanation:
{y = x/2 - 4
y = 1 - 2 x
Substitute y = x/2 - 4 into the second equation:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
In the second equation, look to solve for x:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
Add 2 x + 4 to both sides:
{y = x/2 - 4
(5 x)/2 = 5
Multiply both sides by 2/5:
{y = x/2 - 4
x = 2
Substitute x = 2 into the first equation:
{y = -3
x = 2

The recycling plant processes 480 tons of glass per day.
Step-by-step explanation:
Quantity of glass recycled each minute = 
We know that;
1 hour = 60 minutes
Therefore;
Quantity of glass recycled in one hour = 
1 day = 24 hours
Quantity of glass recycled in 24 hours = 24*20 = 480 tons
The recycling plant processes 480 tons of glass per day.
