Question

solve graphically 2 X - y = 2 , X + 3 y = 15​

Answer 1

Answer:

The plot of the given line equation is (0 , 0) (3 , 4)

Step-by-step explanation:

Given as :

The two linear equation

2 x - y = 2 ......A

x + 3 y = 15 .......B

Solving the equations

(x + 3 y) + 3 × (2 x - y) = 15 + 3 × 2

Or, (x + 6 x) + (3 y - 3 y) = 15 + 6

Or, 7 x + 0 = 21

∴ x = \frac{21}{7}

7

21

i.e x = 3

Put the value of x into A

∵ 2 x - y = 2

Or, 2 × 3 - 2 = y

Or, 6 - 2 = y

i.e y = 4

So, The point of intersection of two equations x , y = 3 , 4

Hence, The plot of the given line equation is (0 , 0) (3 , 4) . Answer
