Find the equation equivalent to 2x=4 which is a multiple of 3
stich3 [128]

we have to find equation similar to

2x=4

Firstly , we can divide both sides by 2

\frac{2x}{2} =\frac{4}{2}

x=2

now, we can multiply both sides by 3

3*x=3*2

we get

3x=6............Answer

Answer:

  • (-4)³ = -64
  • -64

Step-by-step explanation:

The first step in solving the equation is to cube both sides:

  (∛x)³ = (-4)³ . . . . . = (-4)(-4)(-4) = 16(-4) = -64

  x = -64 . . . . . simplified

__

We're not sure what "checking" is supposed to involve here. Usually, one would check the answer by seeing if a true statement is made when the answer is put into the original equation.

  ∛(-64) = -4 . . . true

Many calculators will not compute √(-64) because they compute roots using logarithms. The log of a negative number is not defined.

So, the way one would check this is to cube both sides, which is how we got the answer in the first place. We expect the same result from doing the same operation again, so it isn't really a check.
