9+3.5g=11−0.5g i need this anwser plz help
fiasKO [112]

Answer:

g = 1/2

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

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

9 + 3.5g = 11 - 0.5g

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

  1. Add 0.5g on both sides:                    9 + 4g = 11
  2. Subtract 9 on both sides:                  4g = 2
  3. Divide 4 on both sides:                      g = 1/2

<u>Step 3: Check</u>

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

  1. Substitute in <em>g</em>:                    9 + 3.5(1/2) = 11 - 0.5(1/2)
  2. Multiply:                               9 + 1.75 = 11 - 0.25
  3. Add/Subtract:                      10.75 = 10.75

Here we see that 10.75 does indeed equal 10.75.

∴ g = 1/2 is a solution of the equation.
