Question

If x = -2 and y = -3, then find the value of − 8x + - 2xy + 5.

Answer 1

Answer:

9

Step-by-step explanation:

x= -2 , y = -3

substitute the values in the equation. Then, we get

-8(-2) + -2 (-2)(-3) + 5

= 16 -12 +5

= 9

Answer 2

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

          Given data:- $x=-2$ and $y=-3.$

          To find:- Value of the expression.

           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 -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,

            $-8x+-22xy+5\\=-8(-2)+-22(-2)(-3)+5\\=9.$

            Hence we will get the value $9.$
