Question

2. Write a, b, c for the equation 2y - x = 7
(a) –1, 2, -7 (6) 1, 2, 7
(c) -1, -2, 7 (d) -1, -2, 7​

Answer 1

Answer:

The serial is like this = x,y and z

So, x= -1 ( a)

y = 2 (b)

z = -7 ( c)

According to me the answer is this and it is correct also ....

Answer 2

Option a) has the correct option.

Given:

2y - x = 7

To Find:

The values of a, b and c

Solution:

The given equation 2y - x = 7 can also be written as -x+2y-7=0

It is a linear equation with two variable x and y.. It is in the form of ax +by +c =0 of degree 1 .

On comparing -x+2y-7=0 with the standard equation ax +by +c=0

We get a = -1,b= 2 and c=-7

From the given options ,

Option a) has the correct option.
