Step-by-Step Solution

To solve the given equation 8+2(x+1)=7x 8 + 2(x + 1) = 7x , we'll follow these steps:

  • Step 1: Distribute the 2 2 inside the parentheses.
  • Step 2: Combine like terms and simplify both sides.
  • Step 3: Isolate the variable x x on one side of the equation.

Now, let's apply these steps:
Step 1: Distribute the 2 2 in the equation: 2(x+1)=2x+2 2(x + 1) = 2x + 2 Therefore, the equation becomes: 8+2x+2=7x 8 + 2x + 2 = 7x Step 2: Combine like terms on the left side: 10+2x=7x 10 + 2x = 7x Step 3: Isolate x x by moving all terms involving x x to one side and constants to the other: 10=7x2x 10 = 7x - 2x 10=5x 10 = 5x To solve for x x , divide both sides by 5 5 : x=105=2 x = \frac{10}{5} = 2

Therefore, the solution to the equation is x=2 x = 2 .
