Answer:
star = - 6
Step-by-step explanation:
let the star be s, then
4s = 9s + 30 ( subtract 9s from both sides )
- 5s = 30 ( divide both sides by - 5 )
s = - 6
star = -6
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
