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..
