(12+x)/4 =(-6-x)/2

\frac{12 + x}{4} = \frac{- 6 - x}{2}

x = - 8

Solution steps

\frac{12 + x}{4} = \frac{- 6 - x}{2}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(12 + x) \cdot 2 = 4 (- 6 - x)

Expand

(12 + x) \cdot 2 : 24 + 2 x

Expand

4 (- 6 - x) : - 24 - 4 x

24 + 2 x = - 24 - 4 x

Move

24

to the right side

2 x = - 4 x - 48

Move

4 x

to the left side

6 x = - 48

Divide both sides by

6

x = - 8

4 x + 7 - 5 x = 9

x, 5 x + 7 y = 3

x, 6 x + 6 y = 12

π = π

x, 2 y = 8 x - 6
