Question

check whether the value given in the bracket is a solution to the equation or not 2x+ 1=7 (x=3)​

Answer 1

Yes, the value given in the bracket is a solution to the equation 2x+ 1=7.

Step-by-step explanation:

x=3 is given.

So, on putting this value to eqn. we will get,

2(3)+1

=6+1

=7

So, the value given in the bracket is a solution to the equation 2x+ 1=7.

Answer 2

because when the any question is given like this 2x so its mean 2× ,x = 3 so 2×3 =6 so the answer 2×3 +1 = 7 =6+1=7
