2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y which can be simplified to 6(x + 2y)
9y - 4x
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
2X + 6Y = 12 3X + 9Y = 18 try elimination - 3(2X + 6Y = 12) 2(3X + 9Y = 18) - 6X - 18Y = - 36 6X + 18Y = 36 ================= I will say this system is dependent and an infinite number of solutions can be found.
Y-8x plus 9y equals 10y-8x.
2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y which can be simplified to 6(x + 2y)
9y - 4x
9y + 2x + 3 = 13 + 2xSubtract 2x from each side:9y + 3 = 13Subtract 3 from each side:9y = 10Divide each side by 9:y = 10/9The graph is a straight horizontal line. The slope is zero. The y-intercept is [ y = 10/9 ).
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
3x-2y+9+9y-x = 2x+7y+9
-2x+9y=-35 add 2x to both sides to get 9y=2x-35 divide both sides by 9 to get y=2/9 x - 35/9 the Y intercept is 0, ~-3.889 and the slope is 2/9
It can be simplified to: 9y-2x
(3x - 7y)(2x + 9y)
p + q + r = (2x - 9y) + (5y + 6 - 4x) + (3x + 3y - 5) = x - y + 1
(x - 2)(9y - 2)
It is an algebraic expression that can be simplified to: 5x+9y+5
2X + 6Y = 12 3X + 9Y = 18 try elimination - 3(2X + 6Y = 12) 2(3X + 9Y = 18) - 6X - 18Y = - 36 6X + 18Y = 36 ================= I will say this system is dependent and an infinite number of solutions can be found.
