Question

kindly solve this question. x+x =60, y+y =20 , z+z =4, x+y ÷ z = ? ​

Answer 1

x+x=60

2x=60

x=30

now, y+y=20

2y=20

y=10

and, z+z=4

2z=4

z=2

then, x+y÷z=30+10÷2=30+5=35

Answer 2

Given:

Three equations x+x =60, y+y =20 and z+z =4.

To find:

x + y ÷ z =?

Solution:

To find the value of x + y ÷ z, first of all, we need to find out the value of x, y and z.

So, we have to solve the given equations.

Thus,

As given,

$x + x = 60$

$2x = 60$

$x = 30$

Also,

$y + y = 20$

$2y = 20$

$y = 10$

Similarly, we have

$z + z = 4$

$2z = 4$

$z = 2$

Now, after putting the above values of x, y and z in x + y ÷ z, we have,

$30 + 10 \div 2$

$= 30 + 5$

(using BODMAS rule)

$= 35$

Hence, x + y ÷ z = 35.
