The simplification of – 65x + 4.2y + 65x – 2.2y + 5.4 + y – 3y is 5.4
Solution:
Given, expression is – 65x + 4.2y + 65x – 2.2y + 5.4 + y – 3y
We have to solve the above given expression by combining the like terms.
Then, – 65x + 4.2y + 65x – 2.2y + 5.4 + y – 3y
Combining the like terms in above expression we get,
⇒ ( - 65x + 65x ) + ( 4.2y – 2.2y + y – 3y ) + 5.4
⇒ ( 0 ) + ( 2.0y + ( - 2y ) ) + 5.4
⇒ 0 + (2y – 2y) + 5.4
⇒ 0 + 5.4 = 5.4
Hence, the value of the given expression is 5.4
