(7-2x)/4 =(3(x+5))/9

\frac{7 - 2 x}{4} = \frac{3 ( x + 5 )}{9}

x = \frac{1}{10}

Solution steps

\frac{7 - 2 x}{4} = \frac{3 ( x + 5 )}{9}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(7 - 2 x) \cdot 9 = 4 \cdot 3 (x + 5)

Simplify

(7 - 2 x) \cdot 9 = 12 (x + 5)

Expand

(7 - 2 x) \cdot 9 : 63 - 18 x

Expand

12 (x + 5) : 12 x + 60

63 - 18 x = 12 x + 60

Move

63

to the right side

- 18 x = 12 x - 3

Move

12 x

to the left side

- 30 x = - 3

Divide both sides by

- 30

x = \frac{1}{10}

6 n + 7 = 2 n + 5

3 x^{2} - 3 x + 5 = 0

x^{2} - 14 x + 53 = 9

- (3 x - 12) = 9 x - 4

9 x - 4 x + 4 \geq 36 - 12
