9y-11=7 +11 +11 9y=18 y=2
9y + 10 = - 8 subtract 10 from both sides 9y = -18 Divide by 9 on both sides y = -2
9y - 18 = 3y subtract 3y from both sides 6y - 18 = 0 add 18 to both sides 6y = 18 divide by 6 on both sides y = 3
9y - 9 = -117 9y - 9 + 9 = -117 + 9 9y = -108 9y/9 = -108/9 y= -12
9y = 12.6 y = 1.4
9y-11=7 +11 +11 9y=18 y=2
12y+3=9y-15 3y=-18 y=-6
4y + 10 = -18 4y = -28 y = -7
x=9 y=1
x - 9y = 18At the x-intercept, y=0 :x = 18At the y-intercept, x=0 :-9y = 18-y = 2y = -2
9y + 10 = - 8 subtract 10 from both sides 9y = -18 Divide by 9 on both sides y = -2
9y - 18 = 3y subtract 3y from both sides 6y - 18 = 0 add 18 to both sides 6y = 18 divide by 6 on both sides y = 3
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
Y-8x plus 9y equals 10y-8x.
(y + 6)(y + 3)
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.
9y - 9 = -117 9y - 9 + 9 = -117 + 9 9y = -108 9y/9 = -108/9 y= -12
