Question

Write down the equation for the following expression and then solve it.

Answer 1

Answer:

x = 24

Step-by-step explanation:

x - (3 · 4) = 12

x - 12   =     12

  + 12      + 12

x = 24

Answer 2

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.
