solvefor a,(b-3a)/9 = a/3

solve for

a, \frac{b - 3 a}{9} = \frac{a}{3}

a = \frac{b}{6}

Solution steps

\frac{b - 3 a}{9} = \frac{a}{3}

Apply fraction cross multiply: if

\frac{a}{b} = \frac{c}{d}

then

a \cdot d = b \cdot c

(b - 3 a) \cdot 3 = 9 a

Expand

(b - 3 a) \cdot 3 : 3 b - 9 a

3 b - 9 a = 9 a

Move

3 b

to the right side

- 9 a = 9 a - 3 b

Move

9 a

to the left side

- 18 a = - 3 b

Divide both sides by

- 18

a = \frac{b}{6}

X = \frac{0 + 9.8 \cdot 1 + 1}{2 \cdot ( - 9.8 ) \cdot 1 ^{2}}

c (x) = 45 x + 750

0 = 4 x + 4

x, 3 x - 9 y = 9

x, 3 x + y = 27
