Best ResponseYou've already chosen the best response.1sqrt(x  4) + 9 = 6 sqrt(x  4) = 3 then square it [sqrt(x  4)]^2 = 3^2 x  4 = 9 add 4 x = 13

Best ResponseYou've already chosen the best response.1divide by 6 6sqrt(x + 1) = 24 sqrt(x + 1) = 4 square it [sqrt(x + 1)]^2 = 4^2 x + 1 = 16 subtract 1 x + 1 = 16 x = 15
