<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets

Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

4x - 5 = x - 1 + 3x

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

  1. Combine like terms:                    4x - 5 = 4x - 1
  2. Subtract 4x on both sides:          -5 ≠ -1

Here we see that -5 does not equal -1.

∴ This equation has no solutions.

Makovka662 [10]

Answer:

x + 3 + \frac{13}{x-3}

Step-by-step explanation:

Using long division

                  x + 3  ← quotient

        --------------------------

x - 3 | x² + 0x + 4

          x² - 3x    ↓

        ------------------------

                3x + 4

                 3x - 9

        -----------------------

                        13 ← remainder

Thus

\frac{x^2+4}{x-3} = x + 3 + \frac{13}{x-3}
