    The answer is False

    Explanation:

    The expression is 7-|4 x+1|=-2

    The first step in solving the expression is to bring the expression in the form x=a\ or\ x=-a

    Thus, writing the expression in the form of x=a\ or\ x=-a

    Thus, the first step is to write the expression in the form of x=a\ or\ x=-a

    Thus, Subtracting both sides of the equation by 7, we get,

    -|4 x+1|=-9

    Dividing both sides by -1, we get,

    |4 x+1|=9

    Thus, we have,

    4x+1=9 \ or \ 4x+1=-9

    Hence, the first step of the expression is 4x+1=9 \ or \ 4x+1=-9 which is not equivalent to the equation 7-4 x+1=-2 and 7-4 x+1=2

    Hence, the answer is false.
