solvefor x,(x-y)1/2 =(x+y)3/10

solve for

x, (x - y) \cdot \frac{1}{2} = (x + y) \cdot \frac{3}{10}

x = 4 y

Solution steps

(x - y) \frac{1}{2} = (x + y) \frac{3}{10}

Expand

(x - y) \frac{1}{2} : \frac{x}{2} - \frac{y}{2}

Expand

(x + y) \frac{3}{10} : \frac{3 x}{10} + \frac{3 y}{10}

\frac{x}{2} - \frac{y}{2} = \frac{3 x}{10} + \frac{3 y}{10}

Move

\frac{3 x}{10}

to the left side

\frac{2 x - 5 y}{10} = \frac{3 y}{10}

Multiply both sides by

10

2 x - 5 y = 3 y

Move

5 y

to the right side

2 x = 8 y

Divide both sides by

2

x = 4 y

2 x = \frac{102}{3}

7 (90 - x) = 3 (180 - x) - 10

y, \frac{( d ^{2} \cdot y )}{( d \cdot t ^{2} )} + y = 8 cos (t)

x, x = a \cdot t^{2} + v_{0} \cdot t + x_{0}

x, \frac{p}{( 1 - p )} = \frac{x}{y}
