Transcript text: Let x represent the number. Use the given conditions to write an equation. Solve the equation Three times the sum of three and a number is 60. Find the number.
Write an equation for the given conditions.
$3(x+3) = 60$
Solution
Solution Steps
To solve the problem, we need to:
Translate the given condition into a mathematical equation.
Solve the equation for the unknown variable \( x \).
The condition given is "Three times the sum of three and a number is 60." This translates to the equation \( 3(x + 3) = 60 \).
Solution Approach
Translate the condition into an equation: \( 3(x + 3) = 60 \).
Solve the equation for \( x \).
Step 1: Translate the Condition into an Equation
The given condition is "Three times the sum of three and a number is 60." This translates to the equation:
\[ 3(x + 3) = 60 \]
Step 2: Simplify the Equation
First, distribute the 3 on the left-hand side:
\[ 3x + 9 = 60 \]
Step 3: Solve for \( x \)
Subtract 9 from both sides to isolate the term with \( x \):
\[ 3x = 60 - 9 \]
\[ 3x = 51 \]
Divide both sides by 3 to solve for \( x \):
\[ x = \frac{51}{3} \]
\[ x = 17 \]
