Solve for w.

5w + 9z = 2z + 3w

w = w equals negative StartFraction 7 Over 2 EndFraction z.z
w = w equals negative StartFraction 2 Over 7 EndFraction z.z
w = –2z
w = –7z

Answer:

w=-7/2z

Explanation:

to solve for w you firstly have to group the like terms

5w-3w=2z-9z

2w=-7z

then you have to divide both sides by 2 inorder to remain with w on one side.

2w/2=-7/2

w=-7/2

I hope this helps

Answer:

  • A. w = (-7/2)z or w equals negative StartFraction 7 Over 2 EndFraction z

Explanation:

  • 5w + 9z = 2z + 3w
  • 5w - 3w = 2z - 9z
  • 2w = - 7z
  • w = (-7/2)z

Correct choice is A
