Question 324647
 Solve using substitution:
-y − 5x = -7  --> y = -5x + 7
2y − 2x = 14 -->  y - x = 7
Sub for y in the 2nd equation.
------------------------------

Solve using substitution:
-8x = -4 − y
3y -24x = 8 
Do it like the 1st one.
---------------------------
Solve using elimination:
6x − 2y − 3= 0
4y − 4x = -6 --> -2x + 2y = -3
Add the 2 equaions to eliminate y terms.
-----------------------------
Solve using elimination:
5x − 7y − 1= 0
-10y − 5x = -1 
Multiply the 1st eqn by 2, then add them.
---------------------------
Solve using elimination:
-4y + 2x − 8 = 0
-3x + 6y = 12 

Solve using elimination:
8y = -2x − 16
-x − 4y - 8 = 0
