I believe its 10-6i im pretty sure
Solve for x (isolate/get x by itself)
Add 5 on both sides

Subtract 1/4x on both sides

Make the denominators the same of the fractions in order to combine them. Multiply 2 to the top and bottom of 1/4x

Multiply 8 on both sides

-16 = x
Answer:
Infinite solutions
Step-by-step explanation:
So if simplified it would be
-3x+15=15-3x
Which is basically the same thing if arranged
15-3x=15-3x
-3x+15 can also be 15-3x still the same thing as adding 15 to -3x
So since these are equal anything could be used
like try 0
Both get 15
Try 1
Both get 12
Try legit any number
youll get the same results (I would choose 3 positive easy ones, 0,1,2 and 3 negative ones -1,-2,-3)
