Question

the solution of the equation x-7=4 is​

Answer 1

Answer:

The solution of the equation x - 7 = 4 is x = 11.

Step-by-step explanation:

x - 7 = 4

⇒ x = 4 + 7  [transposing (-7)  from L.H.S. to R.H.S. So it become (+7)]

⇒ x = 11

Answer 2

Given,

An algebraic equation x - 7 = 4.

To find,

The solution of the equation x-7=4 or the value of x.

Solution,

x - 7 = 4 is the equation given.

We have to find the value of x.

The given equation is the linear equation in one variable i.e.  ax+b=c, where a, b and c are constants and x is a variable.

Now, x - 7 = 4,

We can shift -7 from the LHS side of the equation to the RHS of the equations and its sign would change from -7 to +7.

Then we would have,

⇒   x = 7 +4

⇒   x = 11.

Hence. x = 11 is the solution of the equation x - 7 = 4.
