Question

find x and y values: x-12y=-23, x-y=-1

Answer 1

x - 12y = -23 --> x = 12y - 23
x - y = -1 --> x = y - 1
12y - 23 = y - 1
Does that make sense? Can you do the rest?

Answer 2

please, try using the substitution method

Answer 3

from the second equation we have -x+y=1 add this equation and the first equation. You will get the value of y and then putting this value of y in any of the equations, get the value of x. @Blu-Girl

Answer 4

the correct substitution, is:
\[y-1-12y=-23\]
