15z+5+6z=0 21z+5=0 z=-5/21
6z-4z-z = 6-7-4 z = -5
z = 18.5 6z - 24 = 2z + 50 Take the -24 to the other side of the equals and change its sign; take the 2z to the other side of the equals and change its sign: => 6z - 2z = 50 + 24 => 4z = 74 Divide both sides by 4: => z = 18.5
6z + 20
z = 20 (6x20) + (5x20) = 20
6z-513 = -507
-5x+7y-6z
(x + 6z)(x - 6z)
6z + 28 = 12z + 10 18 = 6z 3 = z
6z+28=12z+10 6z-12z=10-28 addition property of equality. -6z=-18 simplification z=3 multiplication property of equality.
If 6z=17, divide both sides by 6 z=17/6
Firstly, we got:(-6z) (102)(-6) (102) (z)-612z-612z is the answer.
17z + 34 = 6z + 5 17z - 6z + 34 = 6z - 6z + 5 11z + 34 = 5 11z + 34 - 34 = 5 - 34 11z = -29 11z/11 = -29/11 z = -2 7/11 or -29/11 Double check your answer: 17z + 34 = 6z + 5 17(-2 7/11) + 34 = 6z + 5 -44 9/11 + 34 = 6z + 5 -10 9/11 = 6z + 5 -10 9/11 = 6(-2 7/11) + 5 -10 9/11 = -15 9/11 + 5 -10 9/11 = -10 9/11 17z + 34 = 6z + 5 when Z = -2 7/11
-6z + 16 = 52 subtract 16 from each side -6z = 36 divide by -6 z = -6
2
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
