Question

Lisa solved the equation x + 6 = 8 + 7x and claimed that the solution is X=-6. Is she

correct? Explain.

Answer 1

Lisa's claim that the solution is x = -6 is incorrect. The correct solution to the equation x + 6 = 8 + 7x is x ≈ 2.33.

Step-by-step explanation:

In the equation x + 6 = 8 + 7x, Lisa claimed that the solution is x = -6. Let's check if this is correct by solving the equation step-by-step:

1. Combine like terms: x - 7x = -6 - 8
2. Simplify: -6x = -14
3. Divide both sides by -6 to isolate x: x = -14 / -6
4. Divide: x = 7/3 or approximately 2.33

So the correct solution to the equation is x ≈ 2.33. Therefore, Lisa's claim that the solution is x = -6 is incorrect.

Answer 2

she is wrong x would be -1/3

Step-by-step explanation:

-6x - 2 = 0

x = -2/6 which is equal to -1/3
