- 20> 8 +7a
Solve inequalities like you would an equation, EXCEPT if you multiply or divide by a negative number, reverse the inequality sign.
Let's look at your problem:
- 20 > 8 + 7a
First subtract 8 from both sides (whatever operation you do to one side you must do to the other side as well):
- 20 - 8 > 8 - 8 + 7a
- 28 > 7a
Divide both sides by 7 to get the variable by itself:
- 28 / 7 > 7a / 7
- 4 > a
I hope this helps.
To solve the inequality - 20 > 8 + 7a, follow these steps:
1. First, subtract 8 from both sides to isolate the term with the variable:
- 20 - 8 > 8 - 8 + 7a
Simplifying this gives:
- 28 > 7a
2. Next, we want to get the variable, "a," by itself. To do this, divide both sides of the inequality by 7:
- 28 / 7 > 7a / 7
Simplifying this gives:
- 4 > a
So, the solution to the inequality is a < -4. This means any value of "a" that is less than -4 will make the inequality true.
