Given: Y = 7 - x
Substitute this value of y to solve for x in the equation: 2x - y = 8
Substitute this value of y to solve for x in the equation: 2x - y = 8
2x - (7 - x) = 8
2x + x - 7 = 8
3x - 7 = 8
3x = 1
x = 1/3
Substitute this value of x in the first equation: Y = 7 - x
y = 7 - 1/3
y = 6.66..
2x + x - 7 = 8
3x - 7 = 8
3x = 1
x = 1/3
Substitute this value of x in the first equation: Y = 7 - x
y = 7 - 1/3
y = 6.66..
