Question

Which should be the first step in solving the equation 1.2 w minus 3.8 = 12.4? Add 3.8 to both sides of the equation. Subtract 1.2 from both sides of the equation. Multiply both sides of the equation by 1.2. Divide both sides of the equation by 3.8.

Answer 1

A

Explanation:

Answer 2

Add 3.8 to both sides of the equation.

Explanation:

12w−3.8=12.4

Add 3.8 to both sides.

12w=12.4+3.8

Add 12.4 and 3.8 to get 16.2.

12w=16.2

Divide both sides by 12.

w= 12/16.2

​Expand 12/16.2 by multiplying both numerator and the denominator by 10.

w= 162/120

​Reduce the fraction 162/120 to lowest terms by extracting and canceling out 6.

w= 27/20 also equal to 1.35
