Question

Substitute the value of x back into the equation x + 3 – 2x = + x + 5 to justify the solution. What value of x is the solution?

Edit: 
Just solved it, 

it's -1.

Answer 1

-1 good luck guys

Explanation:

Answer 2

For this case we have the following equation:

`x + 3 - 2x = x + 5`
The first thing we must do is to group similar terms.
To do this, we write the variables on one side of the equation and the constants on the other side of the equation.
We have then:

`x - 2x - x = 5 - 3`
Rewriting both sides of the equation we have:

`-2x = 2`
When clearing x we have:

`x = (2) / (- 2) x = -1`
Answer:
The value of x that is solution of the equation is:
x = -1
