Question 1087823

Square root 3x-5 (-) square root 4-7x =0
Both 3x-5 and 4-7x are in the square root (not separate)
<pre>{{{matrix(1,3, sqrt(3x - 5) - sqrt(4 - 7x), "=", 0)}}}
Solve this equation to get: {{{matrix(1,3, x, "=", 9/10)}}}
However, as with types of equations like these, YOU MUST CHECK to make sure than the answer SATISFIES the equation.
In this case {{{9/10}}} DOES NOT, so this is an EXTRANEOUS solution, which means that the equation has {{{highlight_green(matrix(1,2, NO, SOLUTIONS))}}}
