Simplify each expression by combining like terms.

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

i dont know sorry
