PLLLZZ HELP ME OUT.WILL GIVE BRAINLIEST... Solving systems of equations using substitution with both equations in y=mx+b

{y,x} = {12,1}

Step-by-step explanation:

Solve equation [2] for the variable  y  

 [2]    y = 12x

Plug this in for variable  y  in equation [1]

  [1]    (12x) - x = 11

  [1]    11x = 11

Solve equation [1] for the variable  x  

  [1]    11x = 11

  [1]    x = 1

By now we know this much :

   y = 12x

   x = 1

Use the  x  value to solve for  y  

   y = 12(1) = 12

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
