Question

3x - 10 = 2 : Solve the equation.

Answer 1

Given: 3x-10=2.

Adding +10 on both the sides:

3x-10+10=2+10.
3x=12.

Dividing both the sides by 3:

3x/3=12/3.
x=4.

We got the value of x as 4.

Let's now check if it is right..

Substituting the value of x with 4:

3(4)-10=2.
12-2=2.
2=2.

Therefore, x=4 is the solution to the equation 3x-10=2.

Answer 2

Given linear equation in one

variable x ,

3x - 10 = 2

Add 10 both sides of the equation ,

we get

=> 3x - 10 + 10 = 2 + 10

=> 3x = 12

divide each term with 3 , we get

=> ( 3x/3 ) = ( 12/3 )

=> x = 4

Therefore ,

x = 4
