9x+6=51 9x = 45 x= 5 9x-6=51 9x = 57 x= 6.33
9x-53=6/x 9x2-53x=6 9x2-53x-6=0 9x2+x-54x-6=0 x(9x+1)-6(9x+1)=0 (9x+1)x(x-6)=0 9x+1=0 or x-6=0 9x=-1 or x=6 x=-1/9 or x=6
9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
12x + 6=9x + 27 12x-9x + 6=9x - 9x + 27 subtract 9x from both sides. 3x + 6 = 27 simplify 3x + 6 - 6=27 - 6 subtract 6 from both sides. 3x=21 simplify 3x/3=21/3 divide both sides by 3 x=7 simplify 12(7) + 6=>84+6=>90 9(7) + 27=>63+27=>90 It checks out!
7x + 6
9x+6=51 9x = 45 x= 5 9x-6=51 9x = 57 x= 6.33
9x + 4 = 6 9x = 6 -4 9x = 2 x = 2/9
9x-53=6/x 9x2-53x=6 9x2-53x-6=0 9x2+x-54x-6=0 x(9x+1)-6(9x+1)=0 (9x+1)x(x-6)=0 9x+1=0 or x-6=0 9x=-1 or x=6 x=-1/9 or x=6
6x2-9x-6 is equal to 66.
-9x+6=y (swap over +6 and y) -9x-y=-6 (when u move numbers or letters over d equal sign u need 2 change signs) 9x+y=6 (chaned all signs) y= 6-9 y= -3 9x+y=6 9x+-3=6 9x=6+3 9x=9 x=9(divided by) 9 x=1 9x+y=6 9+-3=6 So the ordered pair is (1,-3)
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
- 9X + 3Y = - 6 add 9X to each side 3Y = 9X - 6 divide all by 3 Y = 3X - 2
-9x + 4 = -50 -9x = -50 - 4 -9x = -54 -x = -6 x = 6.
9x - 8 = 46 9x = 46 +8 9x= 54 9x/9 = 54/9 x= 6
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
