Question

Please help

Solve 8 = 2x + 4.

What is x?

Solve 64x = 16x−1.

What is x?

Answer 1

hope it helps you!!!!!!!!!!!!

Answer 2

For this case we must find the value of "x" of the following equations:

Equation 1:

`8 = 2x + 4`

We subtract 4 on both sides of the equation:

`8-4 = 2x\\4 = 2x`

We divide between 2 on both sides of the equation:

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

Equation 2:

`64x = 16x-1`

We subtract 16x on both sides of the equation:

`64x-16x = -1\\48x = -1`

We divide between 48 on both sides of the equation:

`x = - \frac {1} {48}`

Answer:

Equation 1:
`x = 2`

Equation 2:
`x = - \frac {1} {48}`
