Question

c) Solve 22x+3 - 9 x 2x+1 = 0​

Answer 1

$\huge\mathbb\purple{QUESTION}$

22x+3 - 9 x 2x+1 = 0

$\huge\mathbb\blue{SOLUTION}$

Add 33 and 11 to get 44 ( 33 + 11 = 44 )

22x+4−9x2x=0

Subtract 44 from both sides. Anything subtracted from zero gives its negation.

22x−9x2x=−4

Combine all terms containing x.

(22−9x2)x=−4

Divide both sides by 22-9x_{2}22−9x2.

$\frac{(22 - 9x2)x}{22 - 9x2} = \frac{ - 4}{22 - 9x2}$

Dividing by 22-9x_{2}22−9x2undoes the multiplication by 22-9x_{2}22−9x2.

$x \ = \frac{ - 4}{22 - 9x2}$

Divide -4−4 by 22-9x_{2}22−9x2.

$x \ = - \frac{4}{22 - 9x2}$
