Okay, so how to explain the problem is that you have to make 135/15 into a unit rate, by doing 135 divided by 15 to equal 9/1, and then you multiply that by 25, and you got your answer, which is 225/25. The 9/1 means 9 berries per 1 minute. The other person got a different answer, but I think this is the correct way to do it, unless I am wrong.

How do you solve this math problem-2(x+3y)=18
ss7ja [257]
Greetings!

Solve for <em>x</em>.
-2(x+3y)=18
Distribute the Parenthesis. <em>How?</em> Multiply all of the terms inside the parenthesis by the number outside the parenthesis.
(-2)*x+(-2)*3y=18
-2x-6y=18
Add 6y to both sides.
(-2x-6y)+6y=(18)+6y
-2x=18+6y
Divide both sides by -2.
(-2x)/-2=(18+6y)/-2
The Answer Is:
x=-9-3y
x=-3y-9

Hope this helps.
