Answer:

y = 16, don't know if I'm 100% right but hope this helps.

Step-by-step explanation:

since they both equal Y they may be equal to each other

Then you would subtract 2x from both sides canceling it out on one side

2x + 8 = 5x - 4

-2x         -2x

This would make the equation 8 = 3x - 4

next you add the 4 from both sides

8  = 3x - 4

+4         +4

This will leave you with 12 = 3x

now you divide 3 from both sides and 12/3 = 4 makes X = 4

next you take (4) and plug it in to one of the equations

y = 2(4) + 8

y = 8 + 8

y = 16

Is -5 2/3 the multiplicative inverse of 3/-17? ​<br><br>PLEASE HELP!!
Ostrovityanka [42]

Answer:

Yes

Step-by-step explanation:

Multiplicative Inverse of rational number:

       When we multiply a rational number and its multiplicative inverse, we get 1

     \sf -5 \dfrac{2}{3}=\dfrac{-17}{3}

  Now,multiply this with (3/-17)

          \sf \dfrac{-17}{3}*\dfrac{3}{-17} = 1

So, -5 2/3  is the multiplicatice inverse of 3/-17
