To solve for variable equations or inequalities, we want to do two things:
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.
The given equation is
.
Let's perform step 1: reducing one side to variables only. By adding
to both sides of the equation, we get 
.
Now let's perform step 2: reducing that side to the variable without coefficients. Since the coefficient of
is 
, we need to divide both sides of the equation by 4: 
. Rounded to the nearest tenth, 
.
So the value of
that satisfies is .
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.
The given equation is
Let's perform step 1: reducing one side to variables only. By adding
Now let's perform step 2: reducing that side to the variable without coefficients. Since the coefficient of
So the value of
1.
60² + 30² = 4500²
Opposite corner = 67.08 ft.
//
2.
6² + 8² = 100²
The wire must be 10 ft.
//
3.
7² + 14² = 245²
The rope is 15.65 ft.
//
4.
180² + 300² = 122400²
He ran 349.85 ft.
//
I'm not too sure about question 3.
