Question

solve graphically the system of linear equation 3 x minus y equal to 2 and X + 2 Y equal 10
​

Answer 1

Answer:

x=2 y= 4

Step-by-step explanation:

3x - y = 2

x+2y= 10

from eqn 2

x= 10 -2y

put value of x in 1

3( 10- 2y ) - y = 2

30 - 6y - y = 2

-7y = -28

y = 4

then put y= 4 in x= 10- 2y

x= 10- 8

x = 2
