Maths Question:-

Solve the pair of linear equation in two variable 2x - y = 10 and 3x +4y = 4 graphically?

Answer 1

Answer:

(2x - y = 10) × 3 —> 2

(3x + 4y = 4) × 2—> 1

Step-by-step explanation:

6x + 8y = 8

6x - 3y = 30

(-) (+) (-)

______________

11y = - 22

y = -22/11

y = -2

2x - y = 10

2x - (-2) = 10

2x + 2 = 10

2x = 10 - 2

2x = 8

x = 8/2

x = 4

so the answer is x = 4 & y = - 2
