x + y = 6 so that -x = y - 6
-x + 3y = -2 that is, y - 6 + 3y = -2 or 4y = 4 or y = 1
and then -x = y - 6 = -5 so that x = 5
y=2

Multiply first equation by 1.5, giving 3x + 3y = 12, but we are told that 3x + 3y = 6. If there isn't an error in the question then 2 = 1!
9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
2x + 3y + 6 = 0Subtract (2x + 6) from each side:3y = -2x - 6Divide each side by 3:y = -(2/3)x - 2Slope = -(2/3)Y-intercept = -2
y=2
4x+3y = 6 3y = -4x+6 y = -4/3x+2 in slope intercept form

The answer is - not are : (5, 1).
-x + 3y = 6 3y = x 6 y = x/3 + 2 So slope = 1/3 and intercept = 2

9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
2x + 3y + 6 = 0Subtract (2x + 6) from each side:3y = -2x - 6Divide each side by 3:y = -(2/3)x - 2Slope = -(2/3)Y-intercept = -2
Collect like terms: 2x + 3y + 3y - 5 - 6 2x + 6y - 11
- 9X + 3Y = - 6 add 9X to each side 3Y = 9X - 6 divide all by 3 Y = 3X - 2
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
10y= 6y+5+3y 10y=6+9y y=6
