If five times a number is subtracted from twelve times a number,
the result is seven less than twice the number.
Find the number.
:
Let n = the number
:
12n - 5n = 2n - 7
12n - 5n - 2n = -7
5n =-7
n = %28-7%29%2F5
n = -1.4 is the number
:
:
See if that checks out
12(-1.4) - 5(-1.4) = 2(-1.4) - 7
-16.8 + 7 = -2.8 - 7
-9.8 = -9.8
