Question

Which value of y forms the solution of the system defined by y = 11x + 1 and 11x + 12y = 12?

Answer 1

The value of y in the solutions is 1, as the y-intercept in the first equation, and in the second after simplifying it.

11x + 12y = 12
12y=11x+12
y=11/12x+1

Answer 2

Answer: The correct answer is : y = 1

Explanation: 1) y = 11 x + 1

2) 11 x + 12 y = 12

Take the value of y from the first equation and replace it in the second equation:

11 x + 12 (11 x + 1) = 12

Reduce :

11 x + 132 x + 12 = 12

Subtract 12 from both sides

11 x + 132 x = 0

143 x = 0

x = 0

Replace this value of x in the first equation:

y = 11 (0) + 1

y = 1
