Question

Solve by using substitution. Express your answer as an ordered pair.

{2x + y = 1
{y = x -5

Answer 1

2x+y=1

y=x-5

substitute: y=x-5 in 2x+y=1

2x+x-5=1

2×+x=1+5

2x+x=6

3x=6

x=6/3

x=2

finding y:

substitute x=2 in 2x+y=1

2×2+y=1

4+y=1

y=1-4

y=-3

so(2,-3) is the answer

Answer 2

All the best this is the answer
