Question:

Solution:

Consider the following equation:

$3x\text{ +2(x-1) = 9x+4}$

applying the distributive property, we get:

$3x\text{ +2x-2 = 9x+4}$

now, putting the like terms together, we obtain:

$3x\text{ +2x -9x = 4 +2}$

this is equivalent to:

$-4x\text{ = 6}$

solving for x, we get:

$x\text{ =- }(6)/(4)\text{ = -}(3)/(2)$

we can conclude that the correct answer is:

$x\text{ =-}(3)/(2)$
