Question

X=1-y, 6x+5y=11 using substitution method

Answer 1

Answer:

x=6 y=-5

Step-by-step explanation:

6x+5y=11

X=1-y

6x=6(1-y)

6x=6-6y

6-6y+5y=11

6-y=11

y=-5

x=1-y

x=1-(-5)

x=6

so,

x=6

y=-5

Answer 2

Answer:

$y = ( - 5) \\ x = 6$

Step-by-step explanation:

$x = 1 - y \\ 6x + 5y = 11 \\ \\ \\ 6(1 - y) + 5y = 11 \\ 6 - 6y + 5y = 11 \\ - 6y + 5y = 11 - 6 \\ - y = 5 \\ y = - 5$

$x = 1 - y \\ x = 1 - ( - 5) \\ x = 1 + 5 \\ x = 6$

Let's check whether the answer is correct.

$6x + 5y = 11 \\ 6 \times 6 + 5 \times ( - 5) = 11 \\ 36 - 25 = 11 \\ 11 = 11$

yes ,its correct
