Question

Solve graphically
a) x+y=10 and x-y=5
b) x+2y=-2 and 3x+2y=2​

Answer 1

Step-by-step explanation:

x+y=10-------------1

x-y=5,---------------2

Equation 1 message subtracting equation 2_____

2x=15

x=15/2

put this value in equation 1____

x+y=10

15/2+y=10

y=10-15/2

y=20-15/2

y=5/2

Answer 2

Answer:

x+y=10

x-y=5

2x=15

x=15/2

x+y= 10

15/2= 10

y= 10-15/2

y=20-15/2

y=5/2
