Answer:
x=7.5 and x=-12.5
Step-by-step explanation:
|2x+5|-4=16
|2x+5|=20
2x+5=20
2x=15
x=7.5
2x+5=-20
2x=-25
x=-12.5
Answer:

Step-by-step explanation:
There are 60 minutes in an hour, thus
56 minutes =
of an hour
To simplify divide 56 and 60 by 4
56 minutes =
← in simplest form
Add the two equations
since the 5x and -5x cancel out
you get y=-4
plug y=-4 into the first equation
solve for x
x=2
THE ANSWER IS: (2,-4)
