Question

Solve for z: 5z + x – y = 3x + 4

Answer 1

z=
`(2x)/(5) + (4)/(5) +(1y)/(5)`

Explanation:

first get the variable z on one side by itself

5z + x – y = 3x + 4

-x -x

5z – y = 2x + 4

+y +y

5z = 2x + 4+y

divide by 5 to get the answer for the variable z

5z = 2x + 4+y

`(5z)/(5) = \frac {2x + 4+y}{5}\\`

z=
`(2x)/(5) + (4)/(5) +(1y)/(5)`

HOPE THIS HELPS:)

Answer 2

z = 2/5x + 1/5y + 4/5

Step 1: Add -x to both sides

Step 2: Add y to both sides

Step 3: Divide both sides by 5
