solvefor x,f=sqrt(k*x-7)

solve for

x, f = k \cdot x - 7

x = \frac{f ^{2} + 7}{k}

Solution steps

f = k x - 7

Square both sides:

f^{2} = k x - 7

f^{2} = k x - 7

Solve

f^{2} = k x - 7 : x = \frac{f ^{2} + 7}{k}

x = \frac{f ^{2} + 7}{k}

x^{2} + x - 8 = x^{2} + x + 4

4 x = 40 - 4 (68 - x^{2})

1 + (x - 2)^{\frac{2}{3}} = 0
