(x+ 3/8 )÷ 2/5 =− 15/8

x = -9/8 = -1 1/8

Step-by-step explanation:

(x+ 3/8 )÷ 2/5 =− 15/8

Copy dot flip

(x+ 3/8 )* 5/2 =− 15/8

Multiply each side by 2/5

(x+ 3/8 )*5/2 *2/5 =− 15/8*2/5

x+3/8 = -3/4

Subtract 3/8 from each side

x+3/8 - 3/8 = -3/4 - 3/8

Get a common denominator

x = -6/8 - 3/8

x = -9/8

x = -1 1/8
