-6z + 16 = 52 subtract 16 from each side -6z = 36 divide by -6 z = -6
6z - 8 - 2 + 3 = 0 combining all the constant terms: 6z -7 = 0 adding 7 to both sides: 6z = 7 dividing both sides by 6: z = 7/6
8z + 3 - 2z < 51 6z + 3 < 51 6z < 48 z < 6 ☺
-6z + 2 = 3z + 4z + 28 Add 6z to both sides: 2 = 3z + 4z + 28 + 6z = 28 + 13z Subtract 28 from both sides: - 26 = 13z Divide both sides by 13: -2 = z
(x + 6z)(x - 6z)
-6z + 16 = 52 subtract 16 from each side -6z = 36 divide by -6 z = -6
6z - 8 - 2 + 3 = 0 combining all the constant terms: 6z -7 = 0 adding 7 to both sides: 6z = 7 dividing both sides by 6: z = 7/6
2z+6z+24=0 8z+24=0 8z= -24 z= - 3
6z =
z = 20 (6x20) + (5x20) = 20
8z + 3 - 2z < 51 6z + 3 < 51 6z < 48 z < 6 ☺
3x 3y + 6z = 12
-6z + 2 = 3z + 4z + 28 Add 6z to both sides: 2 = 3z + 4z + 28 + 6z = 28 + 13z Subtract 28 from both sides: - 26 = 13z Divide both sides by 13: -2 = z
6z-513 = -507
(x + 6z)(x - 6z)
-5x+7y-6z
204 divided by 2 is 102
