Answer:

  • 13x

Step-by-step explanation:

<u>Two ways to solve</u>

1.) Expand each term in the equation

  • 7x = x · x · x · x · x · x · x
  • 6x = x · x · x · x · x · x
  • Count all the x’s ⇒ There are 13 x’s ⇒ 13x

2.) Add the coefficients

  • 7 + 6 = 13
  • 7x + 6x = 13x

Hence,

Answer = 13x

Plz help me with all of this question here and explain how was the incorrect answer obtained
larisa [96]

Answer:

1.) 9

2.) 20

Step-by-step explanation:

1.) 39 is incorrect because they didn't follow the PEMDAS rule.

They subtracted 2 from 15 which is 13, and then they multiplied 13 by 3.

<u>The correct way is to multiply 2 times 3 which is 6, and then subtract 6 from 15 which is 9.</u>

<u />

2.) 12 is incorrect because they didn't use PEMDAS.

They added 8 to 16 which is 24, and then divided 24 by 2.

<u>The correct way is to divide 8 by 2 which is 4, and then add for to 16 which 20.</u>
