Question

In the algebraic expression, $\frac{t}{3}-2=7$, the value of unknown is

• A. 27
• B. 29
• C. 31
• D. 23

Answer 1

The correct option is A 27

Given, $\frac{t}{3}-2=7$
We need to solve t by isolating it to one side of the equation.

Step 1: Add both sides of the equation with 2 to eliminate the constant on the left side of the equation.
$\Rightarrow \frac{t}{3}-2+2=7+2\Rightarrow \frac{t}{3}=9$

Step 2: Now, Multiply both sides by 3 to eliminate 3 on the left side of the equation.
$\Rightarrow \frac{t}{3}\times 3=9\times 3$
$\Rightarrow t=27$

Hence, t = 27
