Question

Solve the inequality below. Use the drop-down menus to describe the solution and its graph.

-7% + 13 > 41

Answer 1

x < -4

Explanation:

I guess that the inequality is:

-7*x + 13 > 41

Solving this is equivalent to isolating x in one side of the inequality.

To do it, we first can subtract 13 in both sides:

-7*x + 13 - 13 > 41 - 13

-7*x > 28

Now we can divide both sides by -7, because we are dividing by a negative number, the direction of the inequality changes:

-7*x/-7 < 28/-7

x < -4

The graph of the solution is an open dot at x = -4 and a line that starts there and goes to the left.
