Step 2.1

Add $2.1 x$ to both sides of the equation.

$- 2.1 x - 4.9 + 2.1 x = - 4.9$

Step 2.2

Add $- 2.1 x$ and $2.1 x$ .

$0 x - 4.9 = - 4.9$

Step 2.3

Multiply $0$ by $x$ .

$0 - 4.9 = - 4.9$

Step 2.4

Subtract $4.9$ from $0$ .

$- 4.9 = - 4.9$

Step 3

Since $- 4.9 = - 4.9$ , the equation will always be true for any value of $x$ .
