Answer:
X = -1
Step-by-step explanation:
6 - 4x = 6x - 8x + 8
-6.                      -6
-4x = -2x + 2
+2x.   +2x
-2x = 2

x = -1
 
        
             
        
        
        
Answer:
y = -2x +20
6x - 5y = 12
Put the value of y in 2nd equation
6x - 5( -2x +20 ) = 12
6x +10x -40 = 12
16x = 12 +40
16x = 52
x = 13/4
Putting the value of x in equation 1
y = -2x +20
y = -2(13/4 ) +20
y = 27/2
