What is the value of x in the equation, 70 = 12 + 9x – 2(x + 6)
lesantik [10]
<h3>Solution :-</h3>

➩ 70 = 12 + 9x - 2 ( x + 6 )

➩ 70 = 12 + 9x - 2x - 12

➩ 70 = 0 + 7x

➩ 70 = 7x

Here we can use 2 methods

Methods :-

  1. Trial and error method :- By adding,subtracting , multiplying or dividing the same variable or constant on LHS & RHS
  2. Transposing :- by transposing a term from LHS to RHS or RHS to LHS

• Trial and error

By dividing with 7 on both sides

➩ 70/7 = 7x/7

➩ x = 10

• Transposing

By transposing 7 from RHS. to LHS

➩ 70/7 = x

➩ x = 10

Hence , x = 10
