If 3z/2 = 9 then the value of z is 6

9+5=14 divided by 7 equals 2

9/1 18/2 27/3 endless possibilities... The result of any number multiplied by 9, then divided by the number equals 9 :-) Any number can be divided by 9 if its sum of digits can be divided by 9.

It's rare to see an equation with two equals signs. I'm guessing something else went in between 3z and 9. 3z + 9 = 15, then z = 2 3z - 9 = 15, then z = 8 3z x 9 = 15, then z = 5/9 3z/9 = 15, then z = 45
If you mean: (3z/7) +9 = -7 then the value of z works out as -37 and 1/3
-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
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7

9 and 3/4 divided by 2/3 equals 14.625
Just testing the numbers 1 to 9, only 1 through 6 result in an even product. Dividing by 7, 8, or 9 results in an uneven number.76380 divided by 1 equals 7638076380 divided by 2 equals 3819076380 divided by 3 equals 2546076380 divided by 4 equals 1909576380 divided by 5 equals 1527676380 divided by 6 equals 1273076380 divided by 9 equals 8486.67 an uneven number.
