Question

Substitute the value of x back into the equation x + 3 -

2x = -1 + 1x + 5 to justify the solution. What value of

x is the solution?

Answer 1

To justify the solution, substitute the value of x back into the equation and solve for x. The value of x in the solution is -1/2.

Step-by-step explanation:

To justify the solution, we substitute the value of x back into the equation x + 3 - 2x = -1 + 1x + 5.

Let's solve it step by step:

Combine like terms on each side:

x + 3 - 2x = -1 + x + 5

-x + 3 = x + 4

Move the x term to one side:

-x - x = 4 - 3

-2x = 1

Divide both sides by -2:

-2x / -2 = 1 / -2

x = -1/2

Hence, the solution is x = -1/2.
