    Firstly, solving the original equation. x/3 = y + 2/3. Multiplying everything by 3 leaves x = 3y + 2.

    Now that we have an equation for x, we can solve the expression (x + 7)/3. Using the formula for x above, x + 7 = (3y + 2) + 7 = 3y + 9. Then, (x + 7)/3 = (3y + 9)/3 = y + 3.

    The answer is (x + 7)/3 = y + 3.

    y+3

  • x / 3= 3y + 2/3

    x = 3y +2

    3y + 2+ y / 3 = 0

    then 3y + 9 = 0

    3y = -9

    then y = -3

    then on substituting in the above equation i got the X value as X = -4

    sub X = -4 Y = -3 in the first equation i just the same on both the sides that is - 4/3 = - 4/3

    thats it !!!!!!!!!!!!!!!!!!!!!

    I have never seen anything like that on an IQ test. I am bad at anything other than basic math skills anyways. I always simplify. But I have yet to score lower than a 115 on an IQ test. Hmmmmm. Odd.

    Source(s): lemme try though: (y+7)+2/3 . really IDK LOL
