Assuming 5z - y = 0, then 5z = y
-8z + 5z = -3z
If you mean: 4+5z+3-8 then it is 5z-1
It is: 5(z+5) = 5z+25
r = 5z 15z = 3y (divide by 3 to both sides) 5z = y r = y
Assuming 5z - y = 0, then 5z = y
-8z + 5z = -3z
If you mean: 4+5z+3-8 then it is 5z-1
(6w - 5z)(6w + 5z)
(6w + 5z)(6w - 5z)
It is: 5(z+5) = 5z+25
(5z - 4)(z - 8) is the solution if the term 44z is negative (5z + 4)(z + 8) is the solution if 44z is positive. It's easier to give a definitive answer if the question is accurately stated.
r = 5z 15z = 3y (divide by 3 to both sides) 5z = y r = y
4z + 2 + 5z - 3 = 9z - 1
8x + 5z - 4x + 3z + 6 = 8x - 4x + 5z + 3z - 6 = 4x + 8z - 6
The following steps lead you to the correct answer: 9z = 5z + 16 9z - 5z = 16 4z = 16 z = 4, thus the correct answer is z = 4
if r=5z and 15z =3 then r=10y
