    Given the equation 5x − 4 = –2(3x + 2), solve for the variable. Explain each step and justify your process.

    ok step one is to remove the parentheses on the right hand side of the equal sign using the distributive property what do you get ?

    do you know the distributive law to remove the parentheses for \[-2(3x+2)\]?

    you have to multiply each term in the parentheses by \(-2\)

    so \[5x-4=-6x-4\]

    next step is to add \(-6x\) to both sides to get rid of it from the left

    what do you get when you add \(6x\) to both sides of the equation ?

    would it be 0 ?

    yes it would, since \(-4+4=0\)

    now you have \[10x=0\] which of course means that \(x=0\)
