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.
4 - 18 divided by 9 equals 2, 2 multiplied by 2 equals 4
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
2x + 9y - 3z = 18At the x-intercept, y' and 'z' are zero.2x = 18x = 9 . . . . . The intercept is (9, 0, 0)At the z-intercept, 'x' and 'y' are zero.-3z = 18z = -6 . . . . . The intercept is (0, 0, -6)The distance between the points is sqrt [ (9)2 + (0)2 + (-6)2 ] = sqrt(117) = 10.8167 (rounded)
