Question

Solve system by substitution {y=-x+5 2x+y=11

Answer 1

y = -1

x = 6

Explanation:

y = -x + 5

2x + y = 11

then:

2x + (-x+5) = 11

2x - x + 5 = 11

x + 5 = 11

x = 11 - 5

x = 6

y = -x + 5

y = -6 + 5

y = -1

Check:

2x + y = 11

2*6 + (-1) = 11

12 - 1 = 11

Answer 2

Answer:x=6,y=−1
