  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

4x + y = 2

y = x - 3

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                    4x + (x - 3) = 2
  2. Combine like terms:           5x - 3 = 2
  3. Isolate <em>x</em> term:                     5x = 5
  4. Isolate <em>x</em>:                              x = 1

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = x - 3
  2. Substitute in <em>x</em>:                       y = 1 - 3
  3. Subtract:                                 y = -2

A rectangle's perimeter is equal to 27 plus its width. The length of the rectangle is four times its width. What is the
lara31 [8.8K]

Answer:

P = 3

Step-by-step explanation:

L = 4*w

P = 27 + w

P = 2*L + 2*w = 27 + w

2L = 2*(4w) = 8w

Put that into the perimeter formula (the first one.)

P = 8w + 2w = 27 + w

10w = 27 + w                        Subtract w from both sides

9w = 27                                Divide by 9

w = 27 / 9                          

w = 3

You should find the Length just so you can check it.

L = 4w

L = 4*3

L = 12

Check

P = 2L + 2w

P = 2*12 + 2*3 = 30

P = 27 + w

P = 27 + 3

P = 30 and everything checks.
