Example 11: Solving Linear Equations

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

Problem

Solve −x+2=4\text{Solve }-x+2=4

1. Recognize Pattern

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

2. Apply Method

3x+6=−9⇒x=−53x+6=-9\Rightarrow x=-5

3. Conclude

x=−2x=-2

Final answer

x=−2x=-2
