solvefor a, 2/((7+3sqrt(5)))=a-b*sqrt(5)

solve for

a, \frac{2}{( 7 + 3 5 )} = a - b \cdot 5

a = \frac{7 - 3 5}{2} + 5 b

Solution steps

\frac{2}{( 7 + 3 5 )} = a - b 5

Switch sides

a - b 5 = \frac{2}{7 + 3 5}

a - b 5 = \frac{2}{7 + 3 5}

Move

b \cdot 5

to the right side

a = \frac{7 - 3 5}{2} + 5 b

b, (b) (- \frac{5}{8})^{x - 9} = 1

11 n + 1 = 1

\frac{x \cdot 18}{100} = 1982.2 x

x, x + 3 = - 2 y + 2

3 + 2 x = 4 - x
