Question

Find solutions of the form x= a , y = 0 and x = 0, y = b for the following pair of equations.
3x + 2y = 6 and 5x - 2y = 10
Do they have any common solution ?
​

Answer 1

Answer:

3x+2y = 6

put y=0, we get 3x+2(0) = 10

3x = 6

x = 6/3 = 2

therefore, (0,3) is a solution

5x+2y = 10

put y = 0, we get 5x+2(0) = 10

5x = 10

y = 10/2

therefore, (0,5) is a solution

the given equations have a common solution (2,0).

.........thank you.........

Answer 2

Answer:

a=2. b=5

Step-by-step explanation:

given,

x=a,y=0 for first equation

x=0,y=b for second equation

sol. 3x+2y=6

3(a)+2(0)=6

3a+0=6

a=2

5x+2y=10

5(0)+2(b)=10

2b=10

b=5
