Question

Помогиие решить систему уравнений
X/2+y/3=6
2x/3-y/3=1

Answer 1

1/2x+y/3=6
2x/3-y/3=1

1/2x×1/3y=6
2x/3-y/3=1

6×1/2x+6×1/3y=6×6
2x/3-y/3=1

3×x+6×1/3y=6×6
2x/3-y/3=1

3×x+2×y=6×6
2x/3-y/3=1

3x+2y=36
2x/3-y/3=1

2y+4x=36
2/3x-y/3

2y+3x=36
3×2/3×-3×1/3y=3

2y+3x=36
2x-3×1/3y=3

2y+3x=36
2x-y=3

(3+4)x=36+2×3
-y+2x=3

7x=36+2×3
-y+2x=3

7x=36+6
-y+2x=3

7x=42
-y+2x=3

x=6
-y+2x=3

x=6
-y+12=3

x=6
-y=3-12

x=6
-y=-9

x=6
y=9
