Question

Solve: -7.1 = 4.1 + w/7

Answer 1

w = -81.2

Explanation:

-7.1 = 4.1 + w/7

7· -11.6=w/7· 7

• I multiplied both sides by 7. which means that the 7 cancels out on the right side and the w is left alone.

w = -81.2

Answer 2

= -78.4

Explanation:

First, you have to subtract 4.1 to -7.1.

-7.1= 4.1+ w/7

-4.1 -4.1

Second, you have to multiply so that you can get the answer for the variable.

7×-11.2= w/7×7

So, the '7x7' cross out and you are left with w= -78.4.
