Solve the equation 5(2x+1)=255(2x+1) = 25

Full solution

Q. Solve the equation 5(2x+1)=255(2x+1) = 25
  1. Distribute 55: Distribute the 55 across the terms inside the parentheses.\newlineWe need to multiply 55 by each term inside the parentheses (2x2x and 11).\newlineCalculation: 5×2x+5×1=10x+55 \times 2x + 5 \times 1 = 10x + 5
  2. Set equal to 2525: Set the distributed expression equal to 2525.\newlineThe equation now looks like this: 10x+5=2510x + 5 = 25
  3. Subtract to isolate: Subtract 55 from both sides of the equation to isolate the term with the variable xx. We want to get xx by itself, so we need to remove the constant term from the left side. Calculation: 10x+55=25510x + 5 - 5 = 25 - 5, which simplifies to 10x=2010x = 20
  4. Divide to solve: Divide both sides of the equation by 1010 to solve for xx. We divide by the coefficient of xx to find the value of xx. Calculation: 10x10=2010\frac{10x}{10} = \frac{20}{10}, which simplifies to x=2x = 2
