Answer:
X = -9/2 Y = 25/6
Step-by-step explanation:
1- X + 3Y = 8
2- 4x+ 6y = 7
1*2 = 2X + 6Y = 16
2*1 = 4x + 6y = 7
--------------------------
-2x = 9
--------------------------
X = -9/2
Substitute x = -9/2 in equation -1
X + 3Y = 8
-9/2 + 3Y = 8
3Y = 8 + 9/2
3Y = 16+9/2
3Y = 25/2
6Y = 25
Y = 25/6
