How do you solve 8x - 7y - (3 - 6y)

Question

 I don't understand can u help me 

Answer 1

Habakkuk, do you know the order of operations?  It's:

 

Parentheses

Exponent

Multiplication

Division

Addition

Subtraction

 

In this case, you might be thrown off because parentheses come first, but here, you can't combine the "unlike terms" (3 and -6y).  So, you can take it out of the parentheses by distributing the minus sign:

 

8x - 7y - 3 + 6y (it's like you multiplied both terms inside the parentheses by -1, and since 2 negatives multiplied make a positive product, it's positive 6y)

 

you can then combine all the y like terms:  

 

y - 3 + 6y

7y - 3

 

You can't combine the - 3 because it doesn't have a y in it, so that's your final answer (there's no solution for y, that's just the most simplified form).
