    Warm-up: Solve each equation

    1. 4x + 5x 2x = 35 2. 2x(3 + 2) = 100

    1.4 Solving MultiStep EquationsI CAN...1.)  solve equations that require 

    multiple steps

    2.)  write and solve multistep equations from real world situations.

    1.4  Solving MultiStep Equations

    Rules for solving multi-step equations1.  You want to isolate the variable (meaning get the variable by 

    itself)

    2. Get rid of parenthesis first.  (meaning use the distributive property)

    3. Combine like terms

    4. Then you need to UNDO the operations being done to the variable AND order matters!

    a. First, undo addition or subtractionb. Second, undo multiplication or division

    5. Don’t forget, whatever you do to one side of the equation has to be done to the other side

    1.4  Solving MultiStep Equations

    Example 1:  Solve each equation.a.   3t + 5t − 5 = 11 b.  10 + 7x – 3 + 5x = 151

    Apr 2312:03 PM

    1.4  Solving MultiStep Equations

    Example 2:  Solve each equation.a.  5a + 3(a + 2) = 22 b.  7(d – 5) + 12 = 5

    Apr 2312:03 PM

    1.4  Solving MultiStep EquationsCheckpoint:  Solve the equation. Check your solution.1.  9d − 4d − 2 = 18 2.  2x + 7(x − 3) = 6

    3.  3w + 4 + w = 36 4.  40 = 4 + 2(10 + 4k)

    1.4  Solving MultiStep Equations

    Example 4:  An online ticket agency charges the amounts shown for basketball tickets.  The total cost for an order is $220.70.  How many tickets are purchased?

    1.4  Solving MultiStep Equations

    Example 5:  The perimeter of the tennis court is 228 feet.  What are the dimensions of the court?  (Hint: P = 2l + 2w)

    w

    2w + 6
