    To break an blueprint for a capricious you charge to get the capricious all by itself. What this agency is you wish the capricious on one ancillary of the according assurance and aggregate abroad on the other. Some examples are below.

    So how do we move numbers around? We do this by adding, subtracting, multiplying, and adding numbers to both abandon of the equation. If we accept the problem 4 + x = 16 we are accustomed to add 6 to both abandon of the blueprint if we capital to. Do not anguish about why yet we will appear to that soon. So now 4 + x = 16 becomes 6 + (4 + x) = (16) + 6. Consistently use the parenthesis, they anticipate you from authoritative mistakes. We can abridge our problem now to 6 + 4 + x = 16 + 6 and then we can abridge it afresh to 10 + x = 22. We can consistently add numbers into a problem as continued as we add the aforementioned amount to both sides.

    Lets attending at the problem x - 4 = 16. If we could abolish the negitive four then we would accept x all by itself and we would understand the band-aid to the problem. To abolish a -4 all we charge to do is add 4 to both sides.

    We yield our problem

    x - 4 = 16

    and add 4 to both sides

    4 + (x - 4) = (16) + 4

    Simplify

    4 + x - 4 = 16 + 4

    Next we use the communative acreage of accession to adapt the 4 and the x.

    x + 4 - 4 = 16 + 4

    Simplify

    x = 20

    We now accept our solution

    So in our archetype (3 + x = 12) we charge to move the three. The accretion changed of three is negitive three so we add negitive three to both abandon of the equation.

    Our blueprint now looks like this:

    -3 + 3 + x = 12 + (-3)

    So if we abridge we get

    x = 9

    Here is addition problem move by step

    x - 8 = 15

    (add the accretion changed of negitive eight to both sides)

    8 + x - 8 = 12 + 8

    (simplify)

    x = 20
