Answer:

A 5

Step-by-step explanation:

Parts on the left have the same ratio as parts on the right.

... x/(x+5) = (x -2)/(x +1)

Multiplying by (x+5)(x+1), we get

... x(x +1) = (x -2)(x +5)

... x² +x = x² +3x -10 . . . . eliminate parentheses

... 0 = 2x -10 . . . . . . . . . . subtract x²+x

... 0 = x -5 . . . . . . . . . . . . divide by 2

... 5 = x . . . . . . . . . . . . . . . add 5

  7. Subtraction
  • Left to Right

Equality Properties

Step-by-step explanation:

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

6n + 7 = 55

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

  1. Subtract 7 on both sides:                    6n = 48
  2. Divide 6 on both sides:                       n = 8

<u>Step 3: Check</u>

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

  1. Substitute in <em>n</em>:                    6(8) + 7 = 55
  2. Multiply:                               48 + 7 = 55
  3. Add:                                     55 = 55

Here we see that 55 does indeed equal 55.

∴ n = 8 is a solution of the equation.
