Question

How do you solve \[2x+8.5=20.4\]?

Answer 1

Hint: For the given question we are given to solve the equation \[2x+8.5=20.4\]. Now we have to consider the equation as equation (1) and then transfer the variable terms at one side and other constant terms at another side to get the value of ‘x’.

Complete step by step solution:
By calling the equation, we get
\[2x+8.5=20.4\]
This is the only equation we have so just we have to find the x coefficient in the simpler way we can so it will be more easier
First we have to write the equation
\[2x+8.5=20.4\]
After writing the equation we have both sides known as right hand side and left hand side
\[2x+8.5=20.4\]
We have to send the numerical which is present on the right hand side to the left hand side
\[\Rightarrow 2x=20.4-8.5\]
The ‘-sign’ becomes ‘+sign’ after switching sides which we mean left hand side to right hand side. Then we have to subtract the numerical which is present on the right hand side
\[\Rightarrow 2x=11.9\]
After subtracting the numerical we have to find x. For finding x we have to switch the side of the x.
\[\Rightarrow x=\dfrac{11.9}{2}\]
We have to continue the process for the next step
\[\Rightarrow x=5.95\]
The above equation is the solution to the given problem

Note: We can do this problem in other ways but we did this problem in this way because this is the easiest process to be done. Students should observe the problem carefully while doing the sum because these model sums are somewhat difficult to do.
