3x + 7= 8
3x= 8-7
3x= 1
x= 1/3
Answer:
=> The value of x is [tex]\frac{1}{3} .[/tex]
Step-by-step explanation:
Given that:-
[tex]3x+7=8[/tex]
To find:- The value of the expression:
Here we will use the transposition method.
We have to follow these steps:-
( i ) First of all, we have to identify the variables and the constants.
( ii ) Get the variable to one side of the equation. Maintain equation balance while calculating.
( iii ) Then solve the expression of both sides by using various mathematical operations. Simplify both sides.
As we have,
=> [tex]3x+7=8[/tex]
Now subtract both sides by [tex]7[/tex], we get
=> [tex]3x+7-7=8-7[/tex]
Simplifying it further, we get
=> [tex]3x=1[/tex]
Divide both sides by [tex]3[/tex], we get
=> [tex]x = \frac{1}{3}[/tex]
Hence, the required solution is [tex]\frac{1}{3} .[/tex]
