r(a)=3r(a/4)+n

r (a) = 3 r (\frac{a}{4}) + n

r = \frac{4 n}{a}; a \neq = 0

Solution steps

r (a) = 3 r (\frac{a}{4}) + n

Expand

r (a) : a r

Expand

3 r (\frac{a}{4}) + n : \frac{3 a r}{4} + n

a r = \frac{3 a r}{4} + n

Multiply both sides by

4

4 a r = 3 a r + 4 n

Move

3 a r

to the left side

a r = 4 n

Divide both sides by

a; a \neq = 0

r = \frac{4 n}{a}; a \neq = 0

16 = - 8 s

15 = - 10 n

2 x + 2 = 20

(x + 8) (x - 2) = (x + 2)^{2}

3 d + 8 = 2 d - 17
