    Simplifying

    3z + -5 + 2z = 25 + -5z

    Reorder the terms:

    -5 + 3z + 2z = 25 + -5z

    Combine like terms: 3z + 2z = 5z

    -5 + 5z = 25 + -5z

    Solving

    -5 + 5z = 25 + -5z

    Move all terms containing z to the left, all other terms to the right.

    Add ‘5z’ to each side of the equation.

    -5 + 5z + 5z = 25 + -5z + 5z

    Combine like terms: 5z + 5z = 10z

    -5 + 10z = 25 + -5z + 5z

    Combine like terms: -5z + 5z = 0

    -5 + 10z = 25 + 0

    -5 + 10z = 25

    Add ‘5’ to each side of the equation.

    -5 + 5 + 10z = 25 + 5

    Combine like terms: -5 + 5 = 0

    0 + 10z = 25 + 5

    10z = 25 + 5

    Combine like terms: 25 + 5 = 30

    10z = 30

    Divide each side by ’10’.

    z = 3

    Simplifying

    z = 3

    Collect like terms:

    3z-5+2z=25-5z

    3z+2z+5z=25+5

    (3+2+5)z = 30

    10z = 30

    z = 3

    Congrates… u gave a right answer.

    3z-5+2z=25-5z Take all ‘z’ terms to one side and numbers to one side, so that you can so addition and substraction.

    The thumb rule: when you transfer any thing from one side of an equal to the other side, the sign which the number contains will change to its opposite. i.e. (+) changes to (-), (*) changes to (/) and vice versa.

    Thus, 3z+2z+5z=25+5

    10z=30

    z=30/10

    Therefore, z=3 BINGO!!

    Best of Luck.

    combine like terms (3z and 2z)

    5z-5 = 25-5z

    add 5z to both sides

    10z-5 = 25

    add 5 to both sides

    10z = 30

    divide both sides by 10

    z = 3

    well you add 5 to both sides to get 3z+2z=30-5z then -2z so 3z=30-7z then + 7z so 10z=30 then simply divide by 10 so 1z=3

    3z+2z+5z=25+5

    10x=30

    x=3

    hint: move all of your Z variables to one side of the equation to simplify and then solve.
