-7(1 + 7n) = 36 - 6n
-7(1) - 7(7n) = 36 - 6n
-7 - 49n = 36 - 6n
<u>   +49n    +49n</u>
   -7 = 36 + 43n
<u>   -36   -36 </u>
      <u>-43</u> = <u>43n</u>
   43    43
      -1 = n

What is the quotient (3x4 + 4x – 15) + (x + 3)?

Hoochie [10]

Answer:

3x-5 and r=0

Step-by-step explanation:

We can do it by long division method the required quotient is 3x-5 and r=0

not 3x-1 , r=1

multiply the divisor with 3x we will get to cancel out the first term of dividend

Now after solving we will get

Now, multiply the divisor by -5 we will get -5x-15 which will cancel the entire dividend.
