Question 407979


{{{sqrt(4x-9) = sqrt(2-x)}}}


{{{(sqrt(4x-9))^2 = (sqrt(2-x))^2}}}

{{{4x-9 = 2-x}}}

{{{4x+x = 2+9}}}

{{{5x = 11}}}

{{{x = 11/5}}}

{{{x = 2.2}}}


check:

{{{sqrt(4(2.2)-9) = sqrt(2-(2.2))}}}


{{{sqrt(8.8-9) = sqrt(-0.2)}}}

{{{sqrt(-0.2) = sqrt(-0.2)}}}

{{{0.45*i=0.45*i}}}
