    -26

    Step-by-step explanation:

    x=7

    3 is being multiplied by X

    replace X with 7 in your equation

    Your equation should then look like this: 3 (7) - 47

    The parentheses around the 7 indicate that the 7 is being multiplied by the 3 or in other words: (3*7) - 47

    multiply 3 and seven before subtracting 47

    3*7 = 21

    Once you have your answer to that subtract 47, your answer should be a negative # because you are subtracting a larger # from a smaller #

    21-47 = - 26

    so if X equals 7. 3x-47 = - 26
