Answer:

x > 6

Explanation:

The first thing you need to know is that when you solve inequalities, imagine the greater than or less than sign as an equal sign as you solve. Use the same rules as you would use in algebra: do the same thing to one side to the other side. Now the equation is writen as 4 + 3x > 22. The first step is to subtract 4 to take it from that side of the equation and isolate the x. Remember that if you divide or multiply by a negative number, you must flip the inequality sign. Now you subract 4 from both sides as we were saying, the equation is now 3x > 18. The last step is to divide 3 from both sides to isolate the variable. The 3 next to the x represents multiplication. The final answer is x > 6

Hope this helped :)
