Answer:
y = 2
Step-by-step explanation:
The mid segment HJ is half of the third side GK , that is
HJ = GK , substitute values
2y = (y + 6) ← multiply both sides by 2 to clear the fraction
4y = y + 6 ( subtract y from both sides )
3y = 6 ( divide both sides by 3 )
y = 2
- 3x+y=8--(1)
2x+4y=12
- x+2y=6--(2)
- (1)×1 and (2)×3
Subtract both
Put the value in eq(2)
