    When you simplify each side of the equation 4(x + 3) = 5 – (x + 1), you will get the equivalent equation 4x + 12 = -x + 4.

    It is not good that correct mathematics is followed by "feel like". If you are sure of your procedure, if you made no error, let's skip the feelings and be confident in the answer. Did you get it right or not?

    if we want 3 consecutive even integers; we could write it like this: 2n-2, 2n, 2n+2 to add these up we have 2n-2 + 2n + 2n+2 = 3*2n = 6n for what value of n does 6n = 42 ??
