For this case we must find the value of "x" of the following equations:
Equation 1:
[tex]8 = 2x + 4[/tex]
We subtract 4 on both sides of the equation:
[tex]8-4 = 2x\\4 = 2x[/tex]
We divide between 2 on both sides of the equation:
[tex]\frac {4} {2} = \frac {2x} {2}\\x = 2[/tex]
Equation 2:
[tex]64x = 16x-1[/tex]
We subtract 16x on both sides of the equation:
[tex]64x-16x = -1\\48x = -1[/tex]
We divide between 48 on both sides of the equation:
[tex]x = - \frac {1} {48}[/tex]
Answer:
Equation 1:[tex]x = 2[/tex]
Equation 2: [tex]x = - \frac {1} {48}[/tex]
