Answer:

\frac{( \frac{5}{8}  +  \frac{3}{4}) }{(  - \frac{ 2}{3}  -  \frac{5}{6} )}  \\  \\  \\  \frac{( \frac{5}{8}  +  \frac{6}{8}) }{( -  \frac{4}{6} -  \frac{5}{6} ) }  \\  \\  \\  \frac{ (\frac{5 + 6}{8}) }{( \frac{ - 4 - 5}{6} )}  =  \frac{( \frac{11}{8} )}{(  - \frac{9}{6} )}  \\  \\  \\  \frac{11}{8}  \div ( -  \frac{9}{6} ) \\  \\  \\  \frac{11}{8}  \times ( -  \frac{6}{9} ) \\  \\  \\  \frac{11}{8}  \times ( -  \frac{2}{3} ) \\  \\  \\   \frac{11}{4}  \times ( -  \frac{1}{3} ) \\  \\  \\  =  -  \frac{11}{12}  \\  \\  \\  =  - 0.91666

2 x 1 x 1/2 = 1
3 x 1 = 3
3 x 2 = 6
3 x 2.2 = 6.6

6.6 + 6 + 3 + 1 + 1 = 17.6

  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right<u> </u>

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Algebra I</u>

  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

y = -7x + 6

y = -10x

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

<em>Substitution</em>

  1. Substitute in <em>y</em> [1st Equation]:                                                                           -10x = -7x + 6
  2. [Addition Property of Equality] Add 7x on both sides:                                   -3x = 6
  3. [Division Property of Equality] Divide -3 on both sides:                                x = -2

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

  1. Substitute in <em>x </em>[2nd Equation]:                                                                         y = -10(-2)
  2. Multiply:                                                                                                             y = 20
