Step 1
We have to use analytical geometry property here.
By analytic Geometry

\Rightarrow 9 (9 + 12) = 7 (7 + x)

\Rightarrow 189 = 49 + 7 x

\Rightarrow 140 = 7 x

x = \frac{140}{7} = 20

Answer:

= 20

Step 1
Factor out x on the left side.

(c - b) x = a

Divide

c - b

to both sides

\frac{(c - b) x}{c - b} = \frac{a}{c - b}

x = \frac{a}{c - b}

Step 1
Given equation:
$9 (9 + 12) = 7 (7 + x)$
Rewrite the equation as:
$7 (7 + x) = 9 (9 + 12)$
Simplify.
Add 9 and 12
$7 (7 + x) = 9 \times 21$
Multiply 9 by 21
$7 (7 + x) = 189$
Divide each term in
$7 (7 + x) = 189$
by 7 and simplify
$\frac{7 (7 + x)}{7} = \frac{189}{7}$
Simplify the left side.
Cancel the common factor.
$\frac{7 (7 + x)}{7} \frac{189}{7}$
Divide 7+x by 1
$7 + x = \frac{189}{7}$
Simplify the right side.
Divide 189 by 7

7+x=27
Move all terms not containing x to the right side of the equation.
Subtract 7 from both sides of the equation.
x=27-7
Subtract 7 from 27
x=20
