Question

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

Answer 1

The correct answer is n = -9.

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
