Answer:
Step-by-step explanation:
First circle 3x-15=12
Ocel’s 10x10=100
Bill’s (10 - y) (10 - y)
I don’t know which answer your teacher wants
100 - [(10-y)(10-y)]
100 - (100 -20y + y^2}
20y - y^2
To solve this, first subtract 6x from both sides.
That is because there cannot be the same variable on both sides of the equation. The new equation would be:
6x=24
Now divide by both sides of the equation by 6
x=4
Hope this helped! Tell me if you have any more questions!
