Question

What is the sum (2/5x + 5/8) + (1/5x - 1/4)?

a. 3/5x + 1/8

b. 3/5x + 3/8

c. 3/5x + 5/8

d. 3/5x + 7/8​

Answer 1

`(3)/(8) + (3x)/(5)`

Explanation:

`\left((2)/(5)x + (5)/(8)\right)+\left((1)/(5)x-(1)/(4)\right)` =

`(2)/(5)x+ (1)/(5)x+ (5)/(8)- (1)/(4)` (Group Like Trems) =

`(3)/(5)x+(5)/(8)-(1)/(4)` =

`(3)/(8)+ (3x)/(5)`
