Question

Solve for w.

5w + 9z = 2z + 3w

Answer 1

5w + 9z = 2z + 3w --- subtract 3w from both sides
5w - 3w + 9z = 2z --- subtract 9z from both sides
5w - 3w = 2z - 9z --- combine like terms
2w = - 7z --- divide by 2 on both sides
w = -7/2z

Answer 2

Answer 3

5w+9z=2z+3w

Add -3w to both sides.

5w+9z+−3w=3w+2z+−3w
2w+9z=2z

Add -9z to both sides.

2w+9z+−9z=2z+−9z
2w=−7z

Divide both sides by 2.

\[ \frac{ 2w }{ 2 }= \frac{ -7z }{ 2 }\]

Answer
w=−72z

Answer 4

* -\[-\frac{ 7 }{ 2 }z\]
