Question

Solve the inequality 2x + 8 < 5x - 4

x > 4

x > 1

x < 1

x < 4

Answer 1

2x +8 < 5x - 4
8 < 5x-2x - 4
8< 3x - 4
8 + 4 <3x
12 < 3x
12 divide by 3 < x
4<x

Answer 2

solve like an equation but if you multiply or divide by a negative, you must change the direction of the sign.

-3 < 1 but if I multiply both sides by (-1) and don't change the direction of the sign, the statement will be false

3 is not less than -1

Answer 3

same as x > 4

Answer 4
