Answer: If two lines are parallel, it means that they have the same slope. Therefore, to find the value of x in this problem, you need to find the slope of line m and line n, and then set them equal to each other.

The slope of a line can be found using the formula:

slope = (y2 - y1)/(x2 - x1)

In this case, you are given the equation of line m in the form "x + 1", and the equation of line n in the form "7x - 5". To find the slope of each line, you can rewrite these equations in the form y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).

For line m, we have:

y = x + 1

The slope of this line is m = 1.

For line n, we have:

y = 7x - 5

The slope of this line is m = 7.

Since line m and line n are parallel, their slopes must be equal. Therefore, we can set these slopes equal to each other and solve for x:

1 = 7

This equation has no solution, which means that there is no value of x that will make these two lines parallel. Therefore, the answer is that there is no solution.
