2/3 (x – 7)= -2 i know x=4 but i need a good show of work for teacher worth 22 points make it worth it

Step-by-step explanation:

⅔ (x – 7) = -2

Let's start by getting rid of the fraction.  Multiply both sides by 3.

2 (x – 7) = -6

Distribute the 2:

2x – 14 = -6

Add 14 to both sides:

2x = 8

Divide both sides by 2:

x = 4

see explanation

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
