Question

find the values of x, if y=3 and y=-3 for the equation 2x-y=3?
​

Answer 1

Step-by-step explanation:

2x - y = 3 and - x + 2y = 3

To find :- (x + y)

2x - y = 3

2x = 3 + y

x = (3 + y)/2

putting value of x in equation (2)

- x + 2y = 3

- (3 + y)/2 + 2y = 3

- (3 + y ) + 4y /2 = 3

- 3 - y + 4y = 6

-3 + 3y = 6

3y = 6 + 3

y = 3

putting value of y in equation (1)

x = (3 + y)/2

x = (3 + 3)/2

x = 6/2

x = 3

x + y = 3 + 3

x + y = 6

hope this will help you

Answer 2

Answer:

i)when value of y=3 then,

2x-3=3

2x=6

x=6/2=3

ii)when value of y= -3 then,

2x-(-3)=3

2x+3=3

2x=3-3=0

x=0

Hope it helps you.
