Q. Solve for x.3x−91>−87 OR 21x−17>25Choose 1 answer:(A) x>2(B) x>34(C) 34<x<2D There are no solutions(E) All values of x are solutions
Solve inequality 3x - 91 > -87: First, let's solve the inequality 3x - 91 > -87. Add 91 to both sides to isolate the term with x. 3x - 91 + 91 > -87 + 91 3x > 4 Now, divide both sides by 3 to solve for x. \frac{3x}{3} > \frac{4}{3} x > \frac{4}{3}
Isolate the term with x: Next, let's solve the inequality 21x - 17 > 25. Add 17 to both sides to isolate the term with x. 21x - 17 + 17 > 25 + 17 21x > 42 Now, divide both sides by 21 to solve for x. \frac{21x}{21} > \frac{42}{21} x > 2
Divide both sides by 3 to solve for x: Now we have two inequalities to consider: x > \frac{4}{3} and x > 2. Since x must be greater than both 34 and 2, we take the larger value, which is 2. Therefore, the solution is x > 2.
