Example 4: Solving Linear Equations

Step-by-step worked example for this lesson track.

Problem

Solve −8x=−56\text{Solve }-8x=-56

1. Recognize Pattern

ax+b=c⇒x=c−baax+b=c\Rightarrow x=\frac{c-b}{a}

2. Apply Method

−8x+6=−42⇒x=6-8x+6=-42\Rightarrow x=6

3. Conclude

x=7x=7

Final answer

x=7x=7
