15 equals 3z-6 the answer?
15 = 3z - 6 15 + 6 = 3z 3z = 21 z = 7
How do you solve 3z plus 2 equals 6z minos 13?
Collect all the letters on one side and the numbers on the other; what you do to one side of the equals you do to the other: 3z + 2 = 6z - 13 → 3z +2 - 3z = 6z - 13 - 3z → 2 = 3z - 13 → 2 + 13 = 3z - 13 + 13 → 15 = 3z → 3z = 15 (this is just changing the equals around so that the letter is on the left) → 3z ÷ 3 = 15 ÷ 5 → z = 5
- 47 plus 6z equals 3z - 2 what does z equal?
-47 + 6z = 3z-2-3z -3z-47 + 3z = -2+47 +473z = 45/3 /3z = 15
What is the answer to -3z-9 equals 24?
-3z - 9 = 24 ⇒ -3z -33 = 0 (subtract 24 from both sides) ⇒ -33 = 3z (add 3z to both sides) ⇒ -11 = z (divide both sides by 3) ie z = -11
What is 3z divided by 7 plus 9 equals minus 7?
If you mean: (3z/7) +9 = -7 then the value of z works out as -37 and 1/3
