Naily [24]3 years ago

The answer is 26. You do 10/1 multiplied by the reciprocal of 5/13 which is 13/5. If you multiply them you get 130/5 which when simplified is 26.

4x - 2y = -20<br> 7x + 2y = -2
Brut [27]

Answer:

(-2, 6)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination
  • Solving systems of equations by graphing

Step-by-step explanation:

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

4x - 2y = -20

7x + 2y = -2

<u>Step 2: Rewrite systems</u>

4x - 2y = -20

  1. Add 2y to both sides:                    4x = 2y - 20
  2. Divide 4 on both sides:                 x = 1/2y - 5

<u>Step 3: Redefine systems</u>

x = 1/2y - 5

7x + 2y = -2

<u>Step 4: Solve for </u><em><u>y</u></em>

<em>Substitution</em>

  1. Substitute in <em>x</em>:                         7(1/2y - 5) + 2y = =-2
  2. Distribute 7:                              7/2y - 35 + 2y = -2
  3. Combine like terms:                11/2y - 35 = -2
  4. Add 35 to both sides:              11/2y = 33
  5. Isolate <em>y</em>:                                   y = 6

<u>Step 5: Solve for </u><em><u>x</u></em>

  1. Define original equation:                    7x + 2y = -2
  2. Substitute in <em>y</em>:                                     7x + 2(6) = -2
  3. Multiply:                                                7x + 12 = -2
  4. Subtract 12 on both sides:                   7x = -14
  5. Divide 7 on both sides:                        x = -2

<u>Step 6: Graph systems</u>

<em>Check the system.</em>
