x/3 =((x+12))/9

\frac{x}{3} = \frac{( x + 12 )}{9}

x = 6

Solution steps

\frac{x}{3} = \frac{( x + 12 )}{9}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

x \cdot 9 = 3 (x + 12)

Expand

3 (x + 12) : 3 x + 36

x \cdot 9 = 3 x + 36

Move

3 x

to the left side

6 x = 36

Divide both sides by

6

x = 6

x, 4 x + 5 y = 20

x, x + 2 y = 0

x, 3 x - 2 y = 10

10 (x + 1) + 32 = 8 x + 5 (x - 3)

24 + 0.44 x = 19 + 1.69 x
