Answer:
1) x < - 1
2) x > 0
3) x < 5
4) x > 3
5) x < - 2
Step-by-step explanation:
1. x < - 1 Form is already simplified.
2. 2x > 0 Divide each term by 2.
= Simplify
= x > 0
3. x + 2 < 7 Isolate x by moving 2 to the right side of the equation.
= x < 7 - 2 Note that the sign of the transposed term must change. Simplify.
= x < 5
4. x - 4 > - 1 Isolate x by moving -4 to the right side of the equation.
= x > -1 + 4 Note that the sign of the transposed term must change. Simplify.
= x > 3
5. 3x + 5 < - 1 First, Isolate x by moving 5 to the right side of the equation.
= 3x < - 1 - 5 Simplify the right side of the equation.
= 3x < - 6
= Divide terms in each side by 3 to completely isolate the x.
= x < - 2
Hope this helps.
