Next step would be 5x10x5
2x - 3 < 9
+ 3
2x < 12
÷ 2
x < 6
Hope this helps!

We can write out a formula in order to solve this. Since sum represents addition, if x represents the unknown number, we can write the formula: x+51=-21. Then, to solve for x, you would subtract 51 from both sides to get x=-72 which is the final answer.
