Question

Solve for x. 2 1/2x−3/4(2x+5)=3/8

A ​ x= −4 5/8 ​

B x= −3 3/8
C x= 4 1/8 ​
D ​ x= 5 3/8 ​

Answer 1

the answer is c

Explanation:

Answer 2

`2 (1)/(2)x- (3)/(4)(2x+5)= (3)/(8)`

`2 (1)/(2)x- (6)/(4)x- (15)/(4)= (3)/(8)`

`( 2(1)/(2)- (6)/(4))x= (3)/(8)+ (15)/(4)`

`( (5)/(2)- (6)/(4))x= (3)/(8)+ (15)/(4)`

`( (10)/(4)- (6)/(4))x= (3)/(8)+ (30)/(8)`

`(4)/(4)x= (33)/(8)`

`x= (33)/(8)=4 (1)/(8)`

Correct answer: C
