Answer 2

Answer:

3x+4y=10.......1

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

Step-by-step explanation:

By substitution method

from eq. 1

3x=10-4y

x=(10-4 y)/3.......3

by putting the value of x in eq. 2 we get

2 {(10-4y)/3)} - 2y=2

(20-8y)/3 - 2y=2

I hope that u can solve it I am just writing the value of y dear

y = -1

By putting y=-1 in eq. 3 we get

x={10-(-1)} /3

x=11/3

By Cross multiplication method we will get
