Math Problem Statement

Solve the following equation for xx. Express your answer in the simplest form. minus, 8, left parenthesis, minus, 8, x, minus, 6, right parenthesis, equals, minus, 2, x, plus, 7 −8(−8x−6)= −2x+7

Solution

We are given the equation:

8(8x6)=2x+7-8(-8x - 6) = -2x + 7

Step 1: Distribute the 8-8 on the left-hand side.

8(8x6)=(8)(8x)+(8)(6)-8(-8x - 6) = (-8) \cdot (-8x) + (-8) \cdot (-6)

This simplifies to:

64x+4864x + 48

Now, the equation becomes:

64x+48=2x+764x + 48 = -2x + 7

Step 2: Move all terms involving xx to one side and constants to the other.

First, add 2x2x to both sides:

64x+2x+48=764x + 2x + 48 = 7

This simplifies to:

66x+48=766x + 48 = 7

Next, subtract 4848 from both sides:

66x=74866x = 7 - 48

This simplifies to:

66x=4166x = -41

Step 3: Solve for xx.

Now, divide both sides by 6666:

x=4166x = \frac{-41}{66}

Final Answer:

x=4166x = \frac{-41}{66}
