Answer:

x = -1

Step-by-step explanation:

2x - 7 = 9x

Subtract 2x from both sides: -7 = 7x

Divide both sides by 7: -1 = x

Now plug in 7 for every value of x in the original equation to make sure you are correct:

2(-1) - 7 = 9(-1)

-2 - 7 = -9

-9 = -9

I hope this helps!

Which equation can be used to solve the following word problem? Seth has 8 more nickels than dimes, and the total value of his c

9966 [12]

Answer:

Seth has 21 nickels

Step-by-step explanation:

Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.

Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then

$5n+10(n-8)=235.$

Solve this equation:

$5n+10n-80=235,\\ \\15n=235+80,\\ \\15n=315,\\ \\n=21.$
