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

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

x = 7

Solution steps

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

Expand

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

Expand

5 (x + 5) : 5 x + 25

15 x - 45 = 5 x + 25

Move

45

to the right side

15 x = 5 x + 70

Move

5 x

to the left side

10 x = 70

Divide both sides by

10

x = 7

\frac{x}{9} = - 6

x, y - 8 = 4 x

x, 2 y + x = - 6

2 x = \frac{1}{2} x - 7

48 = - 8 s
