5x + 2 > 7x - 1
In this scenario, we are solving the inequality.
What this means is that we would need to get x on one side in order to figure out what x is.
Solve:
5x + 2 > 7x - 1
Subtract 7x from both sides
-2x + 2 > -1
Subtract 2 on both sides
-2x > -3
Divide both sides by -2. Flip the inequality since you're dividing by a negative
x < 3/2
In interval notation it would be:
( -∞ , 3/2) or ( -∞ , 1.5)
Answer:
x = 1.5
Step-by-step explanation:
5x + 2 > 7x - 1
5x -7x = -1 -2 (move the terms to the same side, but change the sign on the term being transferred)
-2x = -3 (divide by -2 on both sides)
x = 1.5
