Question

What is the solution to the equation 9(x + 1) = 27

Answer 1

Give it your best shot, first.

Answer 2

x = 2.5
x = 0.5
x = -0.5
x = -3.5

Answer 3

is it A?

Answer 4

o-o None of those are correct.

Answer 5

isnt it supposed to be 2?

Answer 6

9(x + 1) = 27 -- distribute the 9 through the parenthesis
9 * x + 9 * 1 = 27
9x + 9 = 27 -- subtract 9 from both sides
9x + 9 - 9 = 27 - 9
9x = 18
x = 2

check.
9(2 + 1) = 27
9 (3) = 27
27 = 27 (correct)

yep..its 2

Answer 7

or instead of doing all of that ...
9(x + 1) = 27
divide both sides by 9..
x+1 = 3
subtract 1
x = 2

Answer 8

It would actually be 0.5 since the equation is 9^(x + 1) = 27
