7x-9-11=3x+4+2x

how did u get 12?

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
