Divide both sides by -2
two negatives make a positive and that's true so x = 16/2 so divide it
x = 8 because 2 x 8 = 16 and 2/16 = 8 so true.
Answer: x = 8.
And whats the rest of the question

Answer:
(-5, 6) is not a solution.
Step-by-step explanation:
6=2(-5)+4
6=-10+4
-10+4=-6, not 6.
Let u = x², then we would have u² + 5u - 6 = 0
From here, we can factor it and get us (u-1)(u+6) = 0
So our solution for u is u = -6 or 1.
Now substitute u back to x².
x² = -6 or 1
x = ±√(-6) or ±√1
Since ±√(-6) is not real number, we ignore it.
Which leave us x = ±√1 = <span>±1
So our real solution is x = -1 or 1.</span>
