The solution set on the number line.

Solve : \\ \frac { 4x-10 }{ 3 } \\ \frac { 5x-7 }{ 2 } x ∈ R and represent the solution set on the number line.

Solution:

\\ \frac { 4x-10 }{ 3 } \\ \frac { 5x-7 }{ 2 }
⇒ 8x – 20 ≤ 15x – 21
(L.C.M. of 3, 2 = 6)

Solve \frac { 3x }{ 5 } -\frac { 2x-1 }{ 3 } > 1, x ∈ R and represent the solution set on the number line.

Solution:

\frac { 3x }{ 5 } -\frac { 2x-1 }{ 3 } > 1
⇒ 9x – (10x – 5) > 15
⇒ 9x – 10x + 5 > 15
⇒ – x > 15 – 5
⇒ – x > 10
⇒ x < – 10
x ∈ R.
.’. Solution set = {x : x ∈R, x < – 10}
