Question

Find the values of x for which
x + 2 - 2x - 3 < 4
4 3

Answer 1

x > -5

Explanation:

x + 2 - 2x - 3 < 4

↓ group like terms (the x's) on the left side

(x - 2x) + (2 - 3) < 4

↓ combine like terms

-x - 1 < 4

↓ add 1 to both sides

-x < 5

↓ multiply both sides by -1 (and also the sign)

x > -5
