Question

write any two solution for the equation x-2y=5

Answer 1

x+ 2y=5

Put x=0

0+2y=5

2y=5

y=5/2

Now, put y=0

x+2(0)=5

x+0=5

x=5

Hence these are the two solutions for the equation x+2y=5

Answer 2

The two solutions of equation $\bf\:\red{x - 2y = 5}$are (0,-2.5) and (1,-2).

Step-by-step explanation:

Given:

• An equation.
• $x - 2y = 5$

To find:

• Find any two solutions of equation.

Solution:

Concept to be used:

• The equation $\bf ax + by + c = 0$ has infinite many solutions.
• To find the solutions, put value of x and calculate the corresponding value of y; or vice versa.

Step 1:

Find first solution of equation.

Put x=0

$0 - 2y = 5$

or

$- 2y = 5$

or

$y = \frac{ - 5}{2}$

or

$\bf\:y = - 2.5$

One solution of equation is (0,-2.5).

Step 2:

Find second solution of equation.

Put x=1

$1 - 2y = 5$

or

$- 2y = 5 - 1$

or

$- 2y = 4$

or

$y = \frac{ - 4}{2}$

or

$\bf\:y = - 2$

Second solution is (1,-2).

Thus,

Two solutions of given equation are (0,-2.5) and (1,-2).
