equations with unknown variables and it involvessolving for the unknown variable. Variable is an element

which is inconsistent and unlike constants, it keeps changing its values according to the situation. There are

many methods to solve for unknown variables in a given algebraic equation.

To solve for ‘x’, we have to add/subtract few terms on both sides of the equation.

Subtract ‘4x’ on both sides to balance equation 6x – 3–4x = 4x + 11–4x

Now, combine the like terms, this gives 2x – 3 = 11

Add ‘3’ on both sides: 2x – 3 +3 = 11+3

Combine the like terms: 2x= 14

Divide ‘2’ on both sides: 2x/2 = 14/2

To solve for ‘x’, we have to add/subtract few terms on both side of the equation.

Subtract ‘3x’ on both sides to balance equation 8x – 5–3x = 3x + 20 –3x

Now, combine the like terms, this gives 5x – 5 = 20

Add ‘5’ on both sides: 5x – 5 + 5= 20 + 5

Combine the like terms:5x= 25

Divide ‘5’ on both sides:5x/5= 25/5
