The square root of 23, or √23 = <span>4.795831...
</span>
<span>x = {-4, 4}
</span>
<span>Divide each side by '5'.
x2 = 16
Simplifying
x2 = 16
Take the square root of each side:
x = {-4, 4}</span>
The answer/midpoint is 1,5.5
Combine like terms
6x + 9 - 16x
6x - 16x = -10x
-10x + 9 = -21
-9 -9
-10x = -30
-10x/-10 = -30/-10
x = 3
Answer: x = 3
