Answer:
4+x>13
x>9
Step-by-step explanation:
This statement represents an inequality. To solve for the missing number first write out the inequality algebrically.
"Four more" implies that 4 is being added to the number. Another way to "a number" is to use the variable, x. So, the left side of the inequality is 4+x. Then, it says that this is "more than" 13. Thus, the greater than sign, >, should be used. This means that the final inequality is 4+x>13.
Next, you can solve the inequality by subtracting 4 from both sides. This gives x>9.
Distribute the first +a to the +a and multiply, then multiply the same +a and the +b and then multiply the -b and the +a and then the -b and the +b.
