Question

3(b-5)-(a-3b)= 3(b-5)-(b-3)=

Answer 1

Ответ:

3b-15-a+3b=6b-a-15

3b-15-b+3=2b-12

Answer 2

Let's simplify the given expression step by step:

3(b-5) - (a-3b)

Using the distributive property, we can expand the first term:

= 3b - 35 - (a-3b)

= 3b - 15 - (a-3b)

Next, distribute the negative sign to the second term:

= 3b - 15 - a + 3b

Now, let's combine like terms:

= 3b + 3b - a - 15

= 6b - a - 15

So, the simplified expression is 6b - a - 15.

Now, let's simplify the second expression:

3(b-5) - (b-3)

Using the distributive property, we expand the first term:

= 3b - 3*5 - (b-3)

= 3b - 15 - (b-3)

Next, distribute the negative sign to the second term:

= 3b - 15 - b + 3

Combine like terms:

= 3b - b - 15 + 3

= 2b - 12

Therefore, the simplified expression is 2b - 12.
