Step-by-step explanation:
We have, Pair of Linear Equation.
\x - y = 0.†x−y=0
✎ When, x = 1.
x - y = 0.:⟹x−y=0.
1 - y = 0.:⟹1−y=0.
- y = - 1.:⟹−y=−1.
y = 1.:⟹y=1.
✎ When, x = 2.
2 - y = 0.:⟹2−y=0.
- y = - 2.:⟹−y=−2.
y = 2.:⟹y=2.
✎ When, x = 3.
3- y = 0.:⟹3−y=0.
y = 3.:⟹y=3.
3x + 2y - 12= 0.†3x+2y−12=0.
3x + 2 y - 12= 0.:⟹3x+2y−12=0.
\
\✎ When, x = 2.
3(2) + 2 y - 12= 0.:⟹3(2)+2y−12=0.
2 y -6= 0.:⟹2y−6=0.
y = 3.:⟹y=3.
✎ When, x = 4.
3x + 2 y - 12= 0.:⟹3x+2y−12=0.
3(4) + 2 y - 12= 0.:⟹3(4)+2y−12=0.
12 + 2 y - 12= 0.:⟹12+2y−12=0.
y = 0.:⟹y=0.
✎ When, x = - 2.
3x + 2 y - 12= 0.:⟹3x+2y−12=0.
3( - 2) + 2 y - 12= 0.:⟹3(−2)+2y−12=0.
- 6 + 2 y - 12= 0.:⟹−6+2y−12=0.
2 y - 18= 0.:⟹2y−18=0.
\y = 9:⟹y=9
