(x-3)/5 =(x+3)/(15)

\frac{x - 3}{5} = \frac{x + 3}{15}

x = 6

Solution steps

\frac{x - 3}{5} = \frac{x + 3}{15}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(x - 3) \cdot 15 = 5 (x + 3)

Expand

(x - 3) \cdot 15 : 15 x - 45

Expand

5 (x + 3) : 5 x + 15

15 x - 45 = 5 x + 15

Move

45

to the right side

15 x = 5 x + 60

Move

5 x

to the left side

10 x = 60

Divide both sides by

10

x = 6

y, 3 x + 9 y = 63

y, 8 y - 4 x = 24

y, x + 2 y = 14

x + \frac{7}{20} = \frac{4}{5}

y, 5 x + y = - 4
