Answer: x = 19/11
2x + 8 - 5x + 3 = -13 + 8x - 5
Combine like terms on each side:
-3x + 11 = -8 + 8x
Move the variables to one side and the constants to the other side:
-3x - 8x = -8 - 11
Simplify:
-11x = -19
Divide both sides by -11 to solve for x:
x = -19 / -11
Simplify further:
x = 19/11
So, the value of x is 19/11.
