Question

Negative thirteen times a number plus 20 is equal to -11 times the number plus 38

Answer 1

Answer:

The correct answer is n = -9.

Step-by-step explanation:

-13n + 20 = -11n + 38

20 = -11n + 38 + 13n             Add 13n to both sides

20 = 2n + 38                        Combine like terms

20 - 38 = 2n                         Subtract 38 from both sides

-18 = 2n                                 Simplify

-9 = n                                    Divide both sides by 2

OR

-13n + 20 = -11n + 38

-13n = -11n + 38 - 20             Subtract 20 from both sides

-13n = -11n + 18                      Combine like terms

-13n + 11n = 18                       Add 11n from both sides

-2n = 18                                 Simplify

n = -9                                    Divide both sides by -2
