Question

solve this question:
2Z +10 = 25 , Z =
explain in step by step.​

Answer 1

Answer:

z = 7.5 or $\frac{15}{2}$

Step-by-step explanation:

2z + 10 = 25

2z + 10 - 10 = 25- 10 [ Subtracting 10 from both sides]

2z = 15

2z ÷2 = 15 ÷ 2 [ Dividing by two on both sides]

z = 7.5 or $\frac{15}{2}$

Answer 2

• As per the data given in the question, we have to find the value of the expression.

          Given data:- $2z+10=25$

          To find:- Value of the  $z.$

          Solution:-

• Here, we will use the below following steps to find a solution using the transposition method:

• Step 1:- we will Identify the variables and constants in the given simple equation.

• Step 2:-then we Simplify the equation in LHS and RHS.

• Step 3:- Transpose or shift the term on the other side to solve the equation further simplest.

• Step 4:- Simplify the equation using arithmetic operation as required that is mentioned in rule 1 or rule 2 of linear equations.

• Step 5:- Then the result will be the solution for the given linear equation. By using the transposition method. we get,

            $2z+10=25\\\Rightarrow 2z=25-10\\\Rightarrow 2z=15\\\Rightarrow z=\frac{15}{2} \\\Rightarrow z=7.5.$

      Hence we will get the value $z=\frac{15}{2}$ or $7.5.$
