Answer:
x = - 7, y = -4
Step-by-step explanation:
Given-
-2 x + 4 y = -2.......................(i)
-6 x + 8 y = 10.......................(ii)
Multiply by 3 in equation (ii)-
We get -
-6 x + 12 y = -6.....................(iii)
-6 x + 8 y = 10.......................(ii) [ Subtract from equation (iii) to equation (i)]
4 y = -16
y = -4
Put y = - 4 in equation (i)-
-2 x = - 2 - 4 × -4
-2 x = -2 + 16
- 2 x = 14
x = -7
