Question

Write three different solutions of 2x + y =0.
​

Answer 1

Step-by-step explanation:

Given equation 2x−y=7

(i)2x−y=7

If x=2 put the equation we get

2×2−y=7

⇒4−y=7

⇒−y=7−4

⇒y=−3

(2,-3)

(ii)2x−y=7

If x=3 put the equation we get

2×6−y=7

⇒6−y=7

⇒−y=7−6

⇒y=−1

(3,-1)

(i)2x−y=7

If x=4 put the equation we get

2×4−y=7

⇒8−y=7

⇒−y=7−8

⇒y=1

(4,1)

Answer 2

Here is ur answer mate:-

• to find the solution of a equation, means we just have to find the values of x and y.

• Here, as we required 3 different solutions, we have to compute 3 values in the place of either x or y to obtain the solutions of this equation, i.e

→ taking x = 0, we get

2x+y=0

2(0)+y=0

0+y=0

y = 0

So, one solution is (0,0)

→ taking y = 0, we get

2x+y=0

2x+0=0

x = 0/2

So, another solution is (0,0/2)

→ taking x = 1, we get

2x+y=0

2(1)+y=0

2+y=0

y = -2

So, the third solution is (1,-2)

Hence we got all the 3 solution of the equation 2x+y=0. They are -

• 0, 0
• 0, 0/2
• 1/ -2

*u can take any value of either x or y to obtain another's value.
