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

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.

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 doesn't exists.

Step-by-step explanation:

Given: Lily begins solving the equation .

As per question,

Work done by lily is shown here as:

Here, value of variable 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.
