Distribute 5: Distribute the 5 across the terms inside the parentheses.We need to multiply 5 by each term inside the parentheses (2x and 1).Calculation: 5×2x+5×1=10x+5
Set equal to 25: Set the distributed expression equal to 25.The equation now looks like this: 10x+5=25
Subtract to isolate: Subtract 5 from both sides of the equation to isolate the term with the variable x. We want to get x by itself, so we need to remove the constant term from the left side. Calculation: 10x+5−5=25−5, which simplifies to 10x=20
Divide to solve: Divide both sides of the equation by 10 to solve for x. We divide by the coefficient of x to find the value of x. Calculation: 1010x=1020, which simplifies to x=2
