Answer:
Step-by-step explanation:
Given equation:
To solve the equation, the L.H.S must be equivalent to the R.H.S. To prove that L.H.S is equivalent to R.H.S, we have to know the value of "y".
The value of the y variable can be found by isolating the variable from its coefficient. In this equation, the y-variable can be isolated by dividing both sides by four. This cancels the coefficient, isolating the y-variable on one side of the equation.
- ⇒ 4y = 12
- ⇒ 4y/4 = 12/4 (Dividing both sides by 4)
Once the y-variable has been isolated, we can simplify the other side of the variable. The expression/variable/number obtained, on the other side of the equation, is the value of the y-variable.
- ⇒ y = 12/4 (Isolating the y-variable)
- ⇒ y = 3 (Simplifying the R.H.S)
Therefore, the value of y is 3.
