X/9 = 18 multiply through by 9 X = 162 check 162/9 = 18 18 = 18 checks
1 x 18, 2 x 9, 3 x 6.
3 x 6 2 x 9 1 x 18
Working out 50 percent of 18 is the same as working out 18 x 0.5, which is equal to 9.
|x+9|=18 either x+9=18 or x+9=-18 so x=9 or x=-27 When |a|=b then a=b or a=-b
X/9 = 18 multiply through by 9 X = 162 check 162/9 = 18 18 = 18 checks
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1
1 x 18, 2 x 9, 3 x 6.
18 Chairs into equal rows - 6 x 3 2 x 9 18 x 1
16 x 9 x 18 is equal to 2,592.
3 x 6 2 x 9 1 x 18
1 x 18 2 x 9 3 x 6
Working out 50 percent of 18 is the same as working out 18 x 0.5, which is equal to 9.
18 1 + 8 = 9 and 9 x 2 = 18
x2 + 11x + 18 (x + 9)(x + 2) CHECK: x2 + 9x + 2x + 18 x2 + 11x + 18 SET EACH EQUAL TO ZERO: x + 9 = 0 x = -9 x + 2 = 0 x = -2 NOW YOU ARE DONE: Solution set: {-9, -2}
