Answer: y=7,x=3
Steps:
y = 2x + 1
3x + y = 16
Substitute y = 2x + 1
3x + 2x + 1 = 16
Simplify
5x+1=16
Isolate x for 5x + 1 = 16: x = 3
For y = 2x + 1
Substitute x = 3
y = 2 · 3 + 1
Simplify
y = 7
The solutions to the system of equations are:
y = 7, x = 3

You do the reverse and divide the 2 values to find out the last one
72/9 = 8
Do you get it?
Step-by-step explanation:
Assume that
hence,
now,
attached below is the complete solution
Width = w
Length = 2w + 5/2
Perimeter = 2(Length + Width)
Perimeter = 2( w + 2w + 5/2)
Perimeter = 2(3w + 5/2)
Perimeter = 6w + 5
-----------------------------------------------------
Answer: The perimeter is 6w + 5 (Answer D)

The answer is actually choice B. To solve for the area of a trapezoid, you would do the formula a+b/2 h.
