Given the inequalities:
4x-3>5
-2x-7>1
Determine the solution for each inequality.
Solution:
Solve for the inequality separately in terms of x
4x -3 > 5
4x > 5 + 3
4x > 8
x > 2
x is greater than 2
-2x - 7 > 1
-2x > 1 + 7
-2x > 8
In solving for inequalities, whenever a negative number is multiplied or divided, the inequality sign changes. This means that when we divide -2 on both sides of the equation, the inequality sign will change.
x < -4
x is less than -4
