Question

solve the equation and verify the solution ( 2x-1=4 )​

Answer 1

✴Question:

Solve the equation and verify the solution of the given equation.

=> (2x - 1 = 4 )

✴Answer:

2 x - 1 = 4

2 x = 4 + 1

2 x = 5

x = 5/2

=> x = 2.5

Hence the value of x is 2.5 ✔

Now, we have to verify or check whether this solution ie, x = 2.5 suits the above given Equation.

Lets substitute the value now,

2 ( 2.5) - 1

= 5 - 1 = 4 -------=> RHS.

Hence we verified the value of x in the given equation.

✴Note ;

This is linear equation where the unknown variable always takes up a single value.
