7z + 6s + s = 7z + 7s This can then be factorised using 7 as the factor: 7z + 7s = 7(z + s)
2(x - 3y + 7z)
4.2/7=0.6
If Z = 3, then (9 + 7Z) = [ 9 + 7(3) ] = 9 + 21 = 30
7z+9 = 72 7z = 72-9 7z = 63 z = 9
z / (1/7) = 7z.
(7z - 4)(4z - 7) so z = 4/7 or 7/4
2z+9.75-7z=-5.15
7z - 9.4 = 11.6 7z = 11.6 + 9.4 = 21 z = 21/7 = 3
Zx(3+4)= Zx7 = 7z the answer is 7z
The answer to 2Z plus 9.75 subtract 7Z subtract equals 14.90. This is a math problem.
Here's your problem: 3z + 7 = 4z Next, you need to put all of the z's on one side. So you would do this: 3z (-3z) + 7 = 4z (+3z) And you will get this: 7 = 7z Then you will divide each side by 7 in order to find z. (7/7 = 7z/7) The answer will be 1 = z.
