Which equation has the solution x = 3?
8x – 1= 23
Submit Answer
O 82 +1= 21
6x + 3= 81
6x + 7 = -25

Let's solve each equation for x

8x - 1 = 23

Add 1 to each side.

8x = 24

Divide both sides by 8

x = 3

Luckily, we already found the equation which has the solution of x = 3

The answer is: 8x - 1 = 23

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
