Solve the equation for x.arctan (7x- 9) = -1Step 1The original equation arctan (7x - 9) = -1 specifies the arctan of an expression. To solve it, take the tangent of each side and rewrite the equation.tan tan [arctan(7x- 9)]= tan ? tan(-1)Step 2Simplify the above equation. (Round your answers to three decimal places.)7x - =tan( )X =1(tan(-1)+9)/ x=1(-(tan(1)) + 9)/x=
