Question

Make X the subject: 8x+9y=gx+5z​

Answer 1

x =
`(5z-9y)/(8-g)`

Explanation:

Given

8x + 9y = gx + 5z ( subtract gx from both sides )

8x - gx + 9y = 5z ( subtract 9y from both sides )

8x - gx = 5z - 9y ( factor out x on the left side )

x(8 - g) = 5z - 9y ← divide both sides by (8 - g)

x =
`(5z-9y)/(8-g)`
