Question

7. Write five different linear equations in two variables
​

Answer 1

ANSWER

(i) x+y=10

(a) for x=1

1+y=10

y=9

(b) for x=2

2+y=10

y=8

(c) for x=3

3+y=10

y=7

(ii) 2x+y=15

(a) for x=1

2×1+y=15

y=15−2=13

(b) for x=2

2×2+y=15

y=15−4=11

(c) for x=3

2×3+y=15

(iii) 2x−y=0

(a) for x=1

2×1−y=0

y=2

(b) for x=2

2×2−y=0

y=4

(c) for x=3

2×3−y=0

y=6

(iv) 2x−y=1

(a) for x=1

2×1−y=1

y=2−1=1

(b) for x=2

2×2−y=1

y=4−1=3

(c) for x=3

2×3−y=1

y=6−1=5

(v) 2x+3y=0

(a) for x=1

2×1+3y=0

y=−2/3

(b) for x=2

2×2+3y=0

y=−4/3

(c) for x=3

2×3+3y=0

y=−6/3=−2

Answer 2

Hi,

Solution:

A.T.Q.

we ourselves take any 5 linear equation in two variables.

you can take any equation with any coefficient ,but remember don't put any coefficient zero,in that case equation will become linear equation in one variable.

solution of these equations are attached .

just put any value of y, for that value of x will be calculated.

Hope this helps you.
