A number is multiplied by 8, and that product is added to 2. The sum is equal to the product of 2 and 25. Find the number.
LenKa [72]

Answer: the number = 6

Step-by-step explanation:

<u>Let x be the number.</u>

<u>Set equation according to the information given</u>

2 + 8x = 2 × 25

<u>Simplify by multiplication</u>

2 + 8x = 50

<u>Subtract 2 on both sides</u>

2 + 8x - 2 = 50 - 2

8x = 48

<u>Divide 8 on both sides</u>

8x / 8 = 48 / 8

\boxed {x=6}

Hope this helps!! :)
