-9
x . 9 =12-3x9x =12-3x9x+3x=1212x =12x =1
Well if 3x+9=5 x=? Well you minus 9 from the side and then do 5-9 and that equals -4. Then you have to do -4 divided by 3. Which equals -1 so I believe x will equal -1.
Watch closely:6x = 3x + 27Subtract 3x from each side:3x = 27Divide each side by 3:x = 9
Solve this problem -x squared -40x- 80 =0
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
3x-11 for x=9
x - 7 - 9 = -3x - 16 = -3x = 13
-9
24 = 3x + 9 -9 -9 Subtract 9 from each side15 = 3x/3 /3 Divide 3 from each side5 = x You are left with five equals X
x . 9 =12-3x9x =12-3x9x+3x=1212x =12x =1
172=x
3x + 9 = 42 3x = 33 x = 11
3x + 9 = 5x - 43x +13 = 5x13 = 2x13/2 = xso x = 6.5
Well if 3x+9=5 x=? Well you minus 9 from the side and then do 5-9 and that equals -4. Then you have to do -4 divided by 3. Which equals -1 so I believe x will equal -1.
ac + cb = ab = 9 2x - 1 + 3x = 9 5x -1 = 9 So 5x = 10 Thereby x =2. Also ac = 3 and cb = 6
