    Answer:
    144x-227
    Step-by-step explanation:
    4(2x-3)-6x+74(2x-3)-6x+7
    Group like terms: 4(2x-3)+74(2x-3)-6x-6x+7
    Add similar elements: 78(2x-3)-12x+7
    Multiply: (78*2x)+(78*-3) -12x+7= 156x-234-12x+7
    Group like terms: 156x-12x-234+7
    Add the like terms: 156x-12x=144x and -234+7 = -227
    Answer: 144x-227
