Answer:

x = -2

Step-by-step explanation:

2x + 7 = 3

Cancel the 7 by subtracting from both sides

2x + 7 - 7 = 3 - 7

2x = -4

2x / 2 = -4 / 2

x = -2

2/3x - 9 = 6explain work
love history [14]

Here, we are to solve for the value of x in the given euation;

2/(3x-9) = 6

We can solve this by making a cross multiplication

2/(3x-9) = 6/1

The cross-multiplication would yield;

2 * 1 = 6 * (3x-9)

2 = 6(3x-9)

opening the bracket, we have

2 = 18x - 54

Collect like terms;

54 + 2 = 18x

18x = 56

divide both sides by 18

18x/18 = 56/18

x = 28/9

x = 3 1/9

Please help me I promise I will mark Brainliest, I need an answer asap!!!!!!!! please hurry!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Fin
ValentinkaMS [17]

Answer:

D

Step-by-step explanation:

To find the inverse, all we have to do is switch the x and f(x) so instead of f(x)  = 5x + 6, it becomes:

x = 5f(x) + 6

x - 6 = 5f(x)

f⁻¹(x) = (x - 6) / 5
