5-9(1-5r)=5r-3

5 - 9 (1 - 5 r) = 5 r - 3

r = \frac{1}{40}

Solution steps

5 - 9 (1 - 5 r) = 5 r - 3

Expand

5 - 9 (1 - 5 r) : 45 r - 4

45 r - 4 = 5 r - 3

Move

4

to the right side

45 r = 5 r + 1

Move

5 r

to the left side

40 r = 1

Divide both sides by

40

r = \frac{1}{40}

9 x^{2} - 2 x + 9 = 0

(35) (- 415)

x^{2} - 7 x - 8 = 0

x^{2} - x - \frac{3}{2} = 0

e^{x} \cdot e^{- y}
