Question

2x + 3y = 1 and 3y = 5 − x

Answer 1

Answer:

here is your answer

Step-by-step explanation:

3y=5−x

y=(5−x)/3

When x=5,

y=(5−5)/3=0

When x=2,y=(5−2)/3=3/3=1

When x=−1,

y=(5−(−1))/3=6/3=2

x=−1,2,5y=2,1,0Mark the above points on graph. Join them.

2x=y+3 …(ii)

y=2x−3

When x=0,

y=(2×0−3)=0−3=−3

When x=1,

y=(2×1−3)=2−3=−1

When x=2,

y=(2×2−3)=4−3=1

x=0,1,2y=−3,−1,1Mark the above points on graph. Join them.

It is clear from the graph that the two lines intersect at (2,1).

So the solution of the given equations are x=2 and y=

Answer 2

Answer:

-4

Step-by-step explanation:

put value of 3y in 1st eq

2x +5-x =1

x= 1-5

x = -4
