Answer: x - (3 * 4) = 12, x = 24
Step-by-Step Explanation:
Let ‘x’ be the Unknown Number
Framing the Equation :-
=> x - (3 * 4) = 12
Solving the Equation :-
x - (3 * 4) = 12 (First Multiply 3 and 4)
x - (12) = 12 (Now, open the bracket)
x - 12 = 12 (Now, shift 2 to RHS)
x = 12 + 12 (12 becomes positive)
=> x = 24
Hence, the Unknown Number is 24.
