Given the inequality:
5x - 2 > 7
Determine the solutions:
Solution:
In order to determine the solutions of the inequality, we simply must solve for x. To do so, start first by transposing -2 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
5x > 7 + 2
5x > 9
Divide both sides by 5 in order to determine the value of x.
5x/5 > 9/5
x > 9/5 or 1.8
Possible solutions:
1.9, 2, 2.1
Final answer:
Solutions = 1.9, 2, 2.1
