6x-4 = 18
6x = 18+4
6x = 22
x = 22/6 = 3 and 2/3

yes turn the 6x4 sideways and they arevequal tada and ur the smart one ha
U can subtract 18 from each side of the equation.
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
D - 9 = 9 d = 9 + 9 d = 18
(2x10)+3 = 23. (4x5)+3 = 23. (6x4)-1 = 23. etc.
