What is the solution of the system? Use substitution {-4y-3x=-11, x-2y=17}

2)
x=2y+17
1)
4y+3(2y+17)=11
10y+51=11
10y=-40
y=-4

x=2(-4)+17=9
solution: (9,-4)

Solve by substitution: {6x+2y=11, 4x+y=6}.

6x+2(6-4x)=11
6x+12-8x=11
-2x=-1
x=1/2
y=6-4(1/2)=6-2=4
y=4
solution: (1/2, 4)

Use the elimination method to solve the system.

Solution:

 

becomes 
 

 
which means y=-1 

and so... 
 

and thus x=-1 

solution: (-1,-1)
