Question

solve the linear equations graphically x +y=5 and 2x+y=8​

Answer 1

Answer:

Given below. Thanks.

Explanation:

x+y=5

=> x=5-y

Therefore, First Solution, x=3 y=2

Second Solution, x=4 y=1

Therefore, (3, 2) and (4, 1)

2x+y=8

=> x= 8-y/2

Therefore, First Solution, x=2 y=4

Second Solution, x=1 y=6

Therefore, (2, 4) and (1, 6)

Now just plot this on the graph.
