Q. Determine the value of y, if x is 121.y=x−10Answer: y=
Substitute x in equation: Substitute the given value of x into the equation.y=x−10Since x is given as 121, we substitute 121 for x in the equation.y=121−10
Calculate square root: Calculate the square root of 121.121=11This is because 11×11=121.
Subtract 10: Subtract 10 from the square root of 121. y=11−10y=1
