(7+4x)/9 = x/2

\frac{7 + 4 x}{9} = \frac{x}{2}

x = 14

Solution steps

\frac{7 + 4 x}{9} = \frac{x}{2}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(7 + 4 x) \cdot 2 = 9 x

Expand

(7 + 4 x) \cdot 2 : 14 + 8 x

14 + 8 x = 9 x

Move

14

to the right side

8 x = 9 x - 14

Move

9 x

to the left side

- x = - 14

Divide both sides by

- 1

x = 14

s, - 77 = 11 u + 99

\frac{7}{3} x + \frac{6}{3} x = \frac{6}{2} x + \frac{3}{2} x + 8

x = lo g_{3} (53)

(3 x + 4) - (2 x + 9) = 15

(x + 5) (x + 2) - 3 (4 x - 3) = (5 - x)^{2}
