-15/28.4=3x
-15/7=3x
X=3.7/15
=7/5
In simple words what you have to do is first (cross multiply) -15/28 by 4 and x by 3 , as 4.7=28 divide 28 by 4 then it will be -15/7 =3x then as 7 is in the denominator , send it to 3 then it will be 3into 7 unpon 15(3into5 is 15 so divide 15by 3) your ans 7/5

Answer:
-5/7
Step-by-step explanation:
(-15/28)÷x= 3/4
(-15/28) * 1/x = 3/4
-(3*5/4*7) *1/x = 3/4
(-15/28) can also be wrtten as -(3*5/4*7)
now cancel out 3/4
-5/7 *1/x = 1
-5/7 = x
u can cross verify
-(15/28) ÷ (-5/7)
-15/28 * (-7/5) = 3/4
hope ut will help u
