Question

Solve.

3x + 1 < 2x - 2 < 5x +7
A) x < -3 and x > -3
B) -3 < x < 3
C) x < -3
D) no solution

Answer 1

no solution

Explanation:

(you do the exact same you'd do in an equation problem. Get x by itself)

3x+1<2x-2<5x+7

1 < -x-2 < 5x+7

3< -x < 5x+9

3 < -6x < 9

-(1/2) > x > -(3/2)

x can't be bigger than -3 halves and be smaller than -1 half, so the answer is no solution
