Question

One fifth of a number plus five times that number is equal to seven times the number less 18. Find the number and show your work.

Answer 1

Step-by-step explanation:

1/5x + 5x = 7x-18

now that the equation is formed, just find x!

move the whole numbers to one side,

5x-7x+1/5x = -18-1/5x

-2x+1/5x = -18

-1.8x = -18

x = 10

and to find out if 10 is the right value of x, just subsitute 10 back into the very first equation and if it balances out to 0 it ia the right answer. hope i helped!
