We are given:
2x + 5 - 3x = 8(x + 1)
We can start with several things. First, we can combine the x terms on the left side of the equation, and apply the distributive property on the right side of the equation.
5 - x = 8x + 8
Now, we can add x to both sides, and subtract 8 from both sides to isolate the variable.
5 - x = 8x + 8
-8 + x + x -8
We end up with:
9x = -3
By dividing both sides by 9, we get x = .
If you want to check your answer, just plug x in!
2() + 5 - 3(
) = 8(
+ 1)
+ 5 + 1 =
+ 8

As you can see, =
as a result of having x =
