Answer:
I think it's A I'm not sure
The equation given in the question should be written down first and then the process should start for solving and finding the value of the unknown variable "x".
6x + 8 = 2x + 11
6x - 2x = 11 - 8
4x = 3
x = 3/4
The value of the unknown variable "x" comes out to be 3/4. I hope the procedure for solving this equation is clear enough for you to understand. In future you can always use this procedure to get to the solution of similar problems.

Here, Rate of change means Slope and initial value means y-intercept. The equations given above are written in slope-intercept intercept form i.e.

Where,
- m is slope
- b is the y-intercept

- Rate of change = 3
- Initial value = 6

- Rate of change = -7
- Initial value = 5

- Rate of change = 9
- Initial value = 4
