Math Problem Statement

-8(x+5)=-3x-7+x - 3 \

Solution

Let's solve the equation step by step.

Given:

8(x+5)=3x7+x3-8(x+5) = -3x - 7 + x - 3

Step 1: Expand both sides.

On the left side, distribute 8-8 across (x+5)(x + 5): 8x40-8x - 40 On the right side, combine like terms 3x+x-3x + x: 3x+x=2x-3x + x = -2x Now, the equation becomes: 8x40=2x10-8x - 40 = -2x - 10

Step 2: Move all terms involving xx to one side.

Add 8x8x to both sides: 40=6x10-40 = 6x - 10

Step 3: Isolate the constant term.

Add 1010 to both sides: 40+10=6x-40 + 10 = 6x 30=6x-30 = 6x

Step 4: Solve for xx.

Divide both sides by 6: x=306=5x = \frac{-30}{6} = -5

Thus, the solution is: x=5x = -5

Here are 5 related questions to deepen your understanding:

  1. How would the equation change if you distributed 8-8 incorrectly?
  2. What happens if you add variables on both sides instead of moving them?
  3. Can you solve a similar equation with different coefficients?
  4. How does combining like terms on the right side simplify the process?
  5. What if the equation involved fractions instead of whole numbers?

Tip: Always combine like terms before moving variables to simplify equations effectively!
