Hi there!
Looks like a lot of work is going on here.
Let's start by solving this equation for the x.

Step 1) Add -20y to both sides.

Step 2) Divide both sides by 5.


Final Answer:

Now, let's solve for y.
Step 1) Add -5x to both sides.

Step 2) Divide both sides by 20.


Final Answer:

Hope this helps! :D

Answer:
length of BC = 5 1/4 feet
Step-by-step explanation:
Area of a triangle = 1/2×base×height
Area = 4 3/8 square feet
Base = AC= 1 2/3 feet
Height = BC = ?
Area of a triangle = 1/2×base×height
4 3/8 = 1/2 × 1 2/3 × height
35/8 = 1/2 × 5/3 × height
35/8 = 5/6 × height
Height = 35/8 ÷ 5/6
= 35/8 × 6/5
= (35 × 6) / (8 × 5)
= 210 / 40
= 5 1/4 feet
Height = BC = 5 1/4 feet
length of BC = 5 1/4 feet
