<h3>What is simplification?</h3>Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The expression is given below.
⇒ 1/6 (30x + 24) – 1/7 (63 – 7x)
By simplifying we have
⇒ 1/6 × 30x + 1/6 × 24 – 1/7 × 63 + 1/7 × 7x
⇒ 5x + 4 – 9 + x
⇒ 6x – 5
Then the simplification process is done.
