Solution:
The equations can be expressed as
2x-5y+0=0
3x+y-17=0
Use Cramer’s Rule to find the values of x, y, z.
x/Dx = -y/Dy = 1/D
Dx = -5 0
1 -17
=-5×(-17)-0×1
=85+0
=85
Dy = 2 0
3 -17
=2×(-17)-0×3
=-34+0
=-34
D = 2 -5
3 1
=2×1-(-5)×3
=2+15
=17
x/Dx = -y/Dy = 1/D
x/85 = -y/-34 = 1/17
x= 85/17
y= 34/17
x=5 and y=2
Hope this will help.
