Question

Which should be the first step in solving the equation 1.2 w -3.8= 12.4

1. Add 3.8 to both sides of the equation.
2. Subtract 1.2 from both sides of the equation.
3. Multiply both sides of the equation by 1.2.
4. Divide both sides of the equation by 3.8.

Answer 1

add 3.8 to both sides of the equation

Answer 2

Answer:

Option 1 - Add 3.8 to both sides of the equation.            

Step-by-step explanation:

Given : Equation  $1.2w-3.8=12.4$

To find : Which should be the first step in solving the equation?

Solution :

Equation  $1.2w-3.8=12.4$

Step 1 - Adding 3.8 both side,

$1.2w-3.8+3.8=12.4+3.8$

$1.2w= 16.2$

Step 2 - Divide 1.2 both side,

$\frac{1.2w}{1.2}=\frac{16.2}{1.2}$

$w=13.5$

Therefore, The first step in solving the equation is 'Add 3.8 to both sides of the equation.'

So, Option 1 is correct.
