put the value of y in the second equation for y in the first equation \(\bf{-2x-6=-4x+10}\)
mckenzieandjesus
  • mckenzieandjesus
ok
Mehek14
  • Mehek14
now solve for x
mckenzieandjesus
  • mckenzieandjesus
so the -2x-6=-4x+10 is how u add y in the second equation to the first?
Mehek14
  • Mehek14
I put the second equation for y in the first equation
Mehek14
  • Mehek14
so solve for x

  • Mehek14
now can you do the last step?
mckenzieandjesus
  • mckenzieandjesus
what is the next step?
Mehek14
  • Mehek14
-16=-2x how can you solve for x?
mckenzieandjesus
  • mckenzieandjesus
multiply something?
Mehek14
  • Mehek14
divide -16/-2 = x
mckenzieandjesus
  • mckenzieandjesus
-8
Mehek14
  • Mehek14
negative/negative = positive
Mehek14
  • Mehek14
so +8
mckenzieandjesus
  • mckenzieandjesus
ok
mckenzieandjesus
  • mckenzieandjesus
and y is -22?
