Solve 5m - 8 > 12
Solve 12 - 3a > 18
Solve 5m - 4 < 2m + 11
Solve 2r - 18 ≤ 5r + 3
Solve 26p - 20 > 14p + 64
Can someone give me an example to one of these? I don't know how to do these.
Example similar to the first one:
solve 7x-9>61
Add 9 to both sides
7x-9+9 > 61 + 9
7x > 70
Divide by 7 (on both sides)
7x/7 > 70/7
x > 10 [answer]
Sure! Let's take the first equation as an example: 5m - 8 > 12.
To solve this inequality, we need to isolate the variable m. Here are the steps:
Step 1: Add 8 to both sides of the inequality to get rid of the -8 on the left side:
5m - 8 + 8 > 12 + 8
This simplifies to: 5m > 20
Step 2: Divide both sides of the inequality by 5 to isolate the variable m:
(5m)/5 > 20/5
This simplifies to: m > 4
So the solution to the inequality 5m - 8 > 12 is m > 4.
You can follow similar steps to solve the other inequalities you mentioned.
