The Steps Of Algebra.
1. Look
2. Identity The Unknown
3. Solve
4. State The Unknown
Step One:
We Have:
l7xl + 3 ≤ 21.
Step Two:
We Need To Identify X.
Step Three:
Simplify;
First, Subtract Three.
So:
l7xl + 3 ≤ 21
This Becomes:
l7xl ≤ 21-3
21-3 = 18
l7xl ≤ 18
Divide:
7x/7 = 1x = X
So:
X ≤ 18/7
18/7 = 2.57
Which Means:
X ≤ 2.57
Step Four:
X ≤ 2.57 To Make The Equation True.
