Answer:

x =
(y^2-b)/(a)

Explanation:

Given

y =
√(ax+b) ( square both sides )

y² = ax + b ( subtract b from both sides )

y² - b = ax ( isolate x by dividing both sides by a )


(y^2-b)/(a) = x

Answer:


x = \frac{y {}^(2) - b }{a}

Explanation:


y = √(ax + b) \\ y {}^(2) = ax + b \\ ax = y {}^(2) - b \\ x = \frac{y {}^(2) - b }{a}
