Answer:

Step-by-step explanation:

-11x - 72 = 84 + x

combine like terms on opposite side of =

(-11x )+ (-1x) = (84) + (72)

-12x = 156

divide both sides by -12 to isolate x

-12/-12 = 156/-12

x = -13

insert (-13) for x

(-11 * -13) -72 = 84 + (-13)

71 = 71

equality means its right

Find all numbers such that three times the number is greater than eight less than the number.

klio [65]

Answer:

ALL SUCH NUMBERS WHICH ARE GREATER THAN -4 satisfy the given condition.

Step-by-step explanation:

Here, assume such number = m

Now, given :

3 times the number = 3 x ( m) = 3 m

8 less than the given number = m - 8

Now, according to the question:

3 times the number > 8 less than the given number

or, 3 m > m - 8

or, 3m - m > m - 8 + m

or, 2 m > - 8

or, m > - 4

Hence, all SUCH NUMBERS WHICH ARE GREATER THAN -4 satisfy the given condition.
