<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

2(k - 5) + 3k = k + 6

<u>Step 2: Solve for </u><em><u>k</u></em>

  1. Distribute 2:                               2k - 10 + 3k = k + 6
  2. Combine like terms:                  5k - 10 = k + 6
  3. Subtract <em>k</em> on both sides:          4k - 10 = 6
  4. Add 10 on both sides:               4k = 16
  5. Divide 4 on both sides:             k = 4

<u>Step 3: Check</u>

<em>Plug in k into the original equation to verify it's a solution.</em>

  1. Substitute in <em>k</em>:                    2(4 - 5) + 3(4) = 4 + 6
  2. (Parenthesis) Subtract:       2(-1) + 3(4) = 4 + 6
  3. Multiply:                               -2 + 12 = 4 + 6
  4. Add:                                     10 = 10

Here we see that 10 does indeed equal 10.

∴ k = 4 is the solution to the equation.

Zigmanuir [339]

Answer:

Please see the attached picture for the full solution.

*From the 4th line of the 1st image, you could also expand it using

(a +b)²= a² +2ab +b² and

(a -b)²= a² -2ab +b².

When squaring a fraction, square both the denominator and numerator.

➣(a/b)²= a²/b²
