$- 1.7 v + 2.8 = 1.4 v - 3.1 v + 2.8$

Step 1

Since $v$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$1.4 v - 3.1 v + 2.8 = - 1.7 v + 2.8$

Step 2

Subtract $3.1 v$ from $1.4 v$ .

$- 1.7 v + 2.8 = - 1.7 v + 2.8$

Step 3

Move all terms containing $v$ to the left side of the equation.

Step 3.1

Add $1.7 v$ to both sides of the equation.

$- 1.7 v + 2.8 + 1.7 v = 2.8$

Step 3.2

Add $- 1.7 v$ and $1.7 v$ .

$0 v + 2.8 = 2.8$

Step 3.3

Multiply $0$ by $v$ .

$0 + 2.8 = 2.8$

Step 3.4

Add $0$ and $2.8$ .

$2.8 = 2.8$

Step 4

Since $2.8 = 2.8$ , the equation will always be true for any value of $v$ .
