To solve the inequality `2x + 7 < 21`, we need to isolate the variable x.
Subtract 7 from both sides:
2x + 7 - 7 < 21 - 7
2x < 14
Now, divide both sides by 2:
2x/2 < 14/2
x < 7
The solution to the inequality is x < 7.
To graph this inequality on a number line, mark a point at 7 and draw an open circle on it. Then, shade to the left of the circle to indicate that the values of x are less than 7.
