Distribute 3 to terms: Distribute the 3 to both terms inside the parentheses.We have 18=3(t+3). To simplify, we distribute the 3 to t and to 3, which gives us 18=3t+9.
Subtract 9 to isolate: Subtract 9 from both sides of the equation to isolate the term with t. To solve for t, we need to get t on one side of the equation by itself. We do this by subtracting 9 from both sides, which gives us 18−9=3t+9−9.
Simplify both sides: Simplify both sides of the equation.After subtracting 9 from both sides, we get 9=3t.
Divide by 3: Divide both sides of the equation by 3 to solve for t. To isolate t, we divide both sides by 3, which gives us 39=33t.
Find value of t: Simplify both sides of the equation to find the value of t. After dividing by 3, we get 3=t, which means t=3.
