Question

X/5 + 30 = 80 find the value of x​

Answer 1

Answer :

• Value of x is 250

Given :

• x/5 + 30 = 80

To find :

• Value of x

Solution :

⇥ x/5 + 30 = 80

⇥ x/5 + 5 × 30 / 5 = 80

⇥ x + 5 × 30 / 5 = 80

⇥ x + 150 / 5 = 80

⇥ 5 × x + 150 / 5 = 5 × 80

⇥ x + 150 = 5 × 80

⇥ x + 150 = 400

⇥ x = 400 - 150

⇥ x = 250

Hence

Value of x is 250.

Verification :

⇥ x/5 + 30 = 80

⇥ 250/5 + 30 = 80

⇥ 50 + 30 = 80

⇥ 80 = 80

Hence , Verified

Answer 2

• We have to evaluate the above expression by using the given data.

              Given data:- $\frac{x}{5}+30=80.$

              To find:- Value of the expression.

              Solution:-

• Here we will use the transposition method.

• Transposition is one of the linear equations.

• To solve the transposition method we will Identify the variables and constants.

• Then we Simplify the equation in LHS and RHS.

• Now Simplify the equation using arithmetic operations.

        By using the transposition method.

        we get,

                  $\frac{x}{5} +30=80\\=>\frac{x+5\times30}{5} =80\\=>\frac{x+150}{5} =80\\=>x+150=5\times80\\=>x+150=400\\=>x=400-150\\=>x=250.$

       Hence we will get the value $x=250.$
