Lily begins solving the equation 4(x – 1) – x = 3(x + 5) – 11. Her work is shown below. 4(x – 1) – x = 3(x + 5) – 11 4x – 4 – x = 3x + 15 – 11 3x – 4 = 3x + 4

Respuesta :

Solving an equation means finding the value of x which will make the equation true.

We need to undo whatever is done to x to get it by itself.

[tex] 4(x-1)-x = 3(x + 5)-11\\Distributing \; 4 \; and \; 3 \; in \; right \; and \; left \; side \; of \; the \; equation\\\\ 4x-4-x=3x+15-11\\Combine \; like \; terms\\\\3x-4=3x+4\\Subtract \; 3x \; on \; both \; sides\\\\3x-3x-4=3x-3x+4\\ Combine \; like \; terms\\\\-4=4 [/tex]

Conclusion:

Since we end up with an equation which is not TRUE, there is NO solution for this equation. If we graph both the equations, they will end up as a parallel lines which will never meet.

The work shown to find the solution of variable is correct and value of [tex]x[/tex] doesn't exists.

Step-by-step explanation:

Given: Lily begins solving the equation [tex]4(x-1)-x=3(x+5)-11\\[/tex].

As per question,

Work done by lily is shown here as:

[tex]4(x-1)-x=3(x+5)-11 \\4x-4-x = 3x + 15 -11\\3x-4=3x+4[/tex]

Here, value of variable [tex]x[/tex] cant be determined as after solving it to next step the variable vanishes each other.

Therefore, the work shown to find the solution of variable is correct.
