3x + 6 = 5x - 20
Subtract 3x from both sides: 6 = 2x - 20
Add 20 to both sides: 26 = 2x
Divide both sides by 2: 13 = x
3x + 2 = 3x + 6 This is not possible.
what is a slope
x=6
y = 3x + 6slope = 3
X equals 9.
3x + 2 = 3x + 6 This is not possible.
3x+y=6
what is a slope
x=6
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
6-3x+12=0 6+12-3x=0 18-3x=0 18=3x x=6
y = 3x + 6slope = 3
X equals 9.
-3x + 2x = 6Let's abbreviate left part by cancellation:-x = 6The answer will be:x = -6
It is a singular matrix.
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
