Step-by-step explanation:

Plug in your values.

Square 1ft.

Plug this into a calculator or do it manually.

3.5 is rounded to the nearest tenth.
Step-by-step explanation:
=> -3x - 4 = -5y - 8
=> 8 - 4 = 3x - 5y
=> 4 = 3x + (-5)y
=> 1 = (3x/4) + (-5y/4)
=> 1 = x/(4/3) + y/(-4/5)
Compare this with x/a + y/b = 1 where a and b are x & y intercepts.
Here,
x intercept = 4/3
y intercept = -4/5
Answer is x=-3, -1. You have two x values because they are broken down into two equations
