Treat it as a simultaneous equation question:
-2x-10y = -12
3x+y = 4
Multiply all terms in the bottom equation by 10 in order to eliminate y:
-2x-10y = -12
30x+10y = 40
Add both equations together:
28x+0 = 28
Divide both sides of the equation by 28 to find the value of x:
x = 1
Substitute the value of x into the original equations to find the value of y:
x = 1 and y = 1
2x-12
3x+8 = 12 3x = 4 x = 4/3
3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
Point slope equation: Y=3X+12
3x+12=x+48: 3x-x=-12+48 2x=36 x=18
3x - 12 = -2x + 235x = 35 so x = 7
7x = 3x - 12 4x=-12 x=-3
No.
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
y=3x+12
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
