Question

If x = 2, y = 3 and z = 5, find the value of
i) 2x + y + z
ii) 4x – y + z​

Answer 1

Answer:

We will get the value 2x+y+z=12 and 4x-y+z​=10

Step-by-step explanation:

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

        Given data:- $x=2,y=3,z=5.$

       To find:- i) 2x+y+z

                       ii) 4x-y+z​

       Solution:-

• To solve the above equation we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

• BODMAS rule is to be followed while solving expressions in mathematics. it stands for,

           B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

    Now put the values x,y and z in the given equation we get,

        $i)2x+y+z\\=>2+y+z\\=>2(2)+3+5\\=>4+3+5\\=>7+5\\=>12$

        $ii)4x-y+z\\=>4x-y+z\\=>4(2)-3+5\\=>8-3+5\\=>8+2\\=>10$
