Solving Equations with variable on both sides Calculator is used to calculate the value of the variable of those equations that have a term with variable on both sides of the equation

Step 1:- Here we will add 6x to both the sides , we get

=> 6x – 15 = 17 – 6x

=> 6x – 15 + 6x = 17 – 6x +6x

=> 12x – 15 = 17

Step 2:- Add 15 on both the sides

=> 12 x -15 + 15 = 17 + 15

=> 12x = 32

Step 3: - Dividing both the sides by 12

=> 12x /12 = 32 /12

=> x = 8/3

Step 1:- For the given problem: To bring unknown on left side we will subtract both sides by 9

=> 3 x + 9 = x

=> 3x = x - 9

Step 2 :- Subtracting both the sides by x , we will get

=> 2x = -9

Step 3:- Divide both the sides by 2

=> x = -9/2
