1 answer:
Answer: B. 6
Step-by-step explanation:
Let x be the [certain number]
<u />
<u>Rephrase the expression</u>
13 less than fourteen times a certain number is twenty-nine more than 7 times that number
14x-13=7x+29
<u>Calculate</u>
Given
14x-13=7x+29
Add 13 on both sides
14x-13+13=7x+29+13
14x=7x+42
Subtract 7x on both sides
14x-7x=7x+42-7x
7x=42
Divide 7 on both sides
7x/7=42/7
x=6
