1/4 =(400)/(x^2)

\frac{1}{4} = \frac{400}{x ^{2}}

x = 40, x = - 40

Solution steps

\frac{1}{4} = \frac{400}{x ^{2}}

Cross multiply

x^{2} = 1600

Solve

x^{2} = 1600 : x = 40, x = - 40

x = 40, x = - 40

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 40, x = - 40

54.3 = \frac{2 x}{( 0.05 - x ) ^{2}}

y, x = \frac{4 y}{y - 2}

\frac{1}{- b + 3} = \frac{b}{2}

1.5 a^{2} = \frac{( 6 )}{( a ^{2} )}

y, \frac{5 y}{7 y - 3} = x
