Question

solve the equation x - 5 = 7 and check the result​

Answer 1

☆ Solution :

▪︎x - 5 = 7《Linear Equation in one variable find x》

》x = 7 + 5《-5 goes to RHS gets plus and just add it with 7》

》x = 12

☆ CHECKING MY RESULT

▪︎x - 5《Verifying》

= 12 - 5《x = 12》

= 7《LHS = RHS as the RHS is 7 then LHS is also 7》

▪︎So, The value of variable x is 12 [Confirmed].

I HOPE YOU GOT IT :D

Answer 2

Answer:

Solution:

x - 5 = 7

= x - 5 + 5 = 7 + 5 [ adding 5 to both the sides ]

= x = 12

So, x = 12 is the solution of the given equation.

Checking:

Substituting x = 12 in the given equation, we get

LHS = 12 - 5 = 7 and RHS = 7

Therefore, when x = 12, we have : LHS = RHS
