What is the solution for x if sqrt parentheses 4x plus 7 endparentheses minus 4 equals sqrt parentheses 4x minus 1 endparentheses?
Drew333
sqrt(4x+7) -4 = sqrt(4x-1)
squared : (sqrt(4x+7) -4)2 = 4x-1
(4x+7) - 2x4xsqrt(4x+7) +16 = 4x-1
-8xsqrt(4x+7) = -24
sqrt(4x+7) = -24/-8 = 3
squared : 4x+7 = 32 = 9
4x = 9-7 = 2 then x=1/2
