Question

1. Which one of the following equations has the solution n = 10? *
a. 2n + 4 = 3n + 5
b. 70 − 6n = n
c. 50 − 4n = 90
d.4 − n = 6

Answer 1

Answer:

d. n(n+4)

Step-by-step explanation:

Answer 2

Answer:

b. 70 - 6n = n

Step-by-step explanation:

70 - 6n = n

70 = n + 6n

70 = 7n

70 ÷ 7 = n

n = 10
