Question

Solve graphically, the following equations:
2x + y - 3 = 0 and 2x – 3y – 7 = 0​

Answer 1

Explanation:

from eq( i)2x+y=3

put x=0,y=3

put x=1,y=2

from eq( ii)

2x-3y=7

put y=1,x=5

put y=3,x=8

now you can obtain graph by these value

Answer 2

Answer:

x = 2

y = -1

Explanation:

2x + y = 3 × 3

2x - 3y = 7 × 1

6x + 3y = 9

2x - 3y = 7

8x = 16

x = 16/8

x = 2

2x + y = 3

y = 3 - 2x

y = 3 - 2*2

y = 3 - 4

y = -1
