Question

Which line shows the first error in the solution?

Answer 1

Answer:

The first line.

Step-by-step explanation:

If we let x represent "a number", then "a number divided by 3" is x/3. The denominator is missing on the first line.

Further, this "is 4 more than -11", so is = 4 + (-11). The constant 4 is on the wrong side of the equal sign in line 1.

_____

The solution should be ...

... x/3 = 4 + (-11)

... x = 3·(-7)

... x = -21

___

Check

-21 divided by 3 is -7. That is 4 more than -11.
