Answer:

star = - 6

Step-by-step explanation:

let the star be s, then

4s = 9s + 30 ( subtract 9s from both sides )

Answer:

star = -6

Step-by-step explanation:

Let the star = x

4x = 9x+30

Subtract 9x from each side

4x-9x = 9x-9x+30

-5x = 30

Divide by -5

-5x/-5 = 30/-5

x = -6

Check:

4(-6) = 9*-6 +30

-24 = -54 +30

-24 = -24

Yes, it is the solution
