Question

One equation of a pair of dependent linear equations is 2x + 5y = 3. The second equation will be (a) 2x + 5y = 6 (b) 3x + 5y = 3 (c) -10x – 25y + 15 = 0 (d) 10x + 25y = 15

Answer 1

Answer:

(c)-10x-25y+15=0

Step-by-step explanation:

Given:

2x+5y=3

if u multiply by 5 the whole given term

you'll get

10x+25y=15

bring 15 to left hand side

10x+25y-15=0

multiply by -ve sign

-10x-25y+15=0

Answer 2

Given : One equation of a pair of dependent linear equations is

2x + 5y = 3.

To Find :  second equation can will be:​

(a) 2x + 5y = 6

(b) 3x + 5y = 3

(c) -10x – 25y + 15 = 0

(d) 10x + 25y = 15

Solution:

a pair of dependent linear equations is having two equations of lines representing the same line

Hence having Infinite solutions

a pair of dependent linear equations can be  written as

Ax  + By = C

KAx + KBy  = KC

where K is non zero real number

2x + 5y = 3

Multiplying by 5 on both sides

10x + 25y  = 15

Hence option d) is correct

Multiplying by - 1 both sides

=> -10x - 25y = - 15

Transposing -15 on LHS

=> -10x - 25y + 15 = 0

Hence option c) is also correct

Option c and d are correct
