Answer:

x = 12

Step-by-step explanation:

Given expression is \[7x-9-11=3x+4+2x\]

Simplifying: \[7x -(9+11) = (3x+2x)+4\]

Or, \[7x - 20 = 5x + 4\]

Bringing all terms containing x to the left side of the equation and all the numeric terms to the right side:

\[7x-5x = 20 + 4\]

=> \[(7-5)x = 24\]

=> \[2x = 24 \]

=> x = \[\frac{24}{2}\]

=> x= 12

Hence the value of x which satisfies the given equation \[7x-9-11=3x+4+2x\] is 12
