Answer:
y = ± ![\sqrt{\frac{a-x}{2b} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Ba-x%7D%7B2b%7D%20%7D)
Step-by-step explanation:
Given
x = a - 2by² ( add 2by² to both sides )
x + 2by² = a ( subtract x from both sides )
2by² = a - x ( divide both sides by 2b )
y² =
( take the square root of both sides )
y = ± ![\sqrt{\frac{a-x}{2b} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Ba-x%7D%7B2b%7D%20%7D)
