Question

Solve the proportion ASAP help do both questions

Answer 1

7. 4

8. 7

Explanation:

7.
`(1)/(2) = (x)/(8)`

Cross multiply

`1*8 = x*2`

`8 = 2x`

`(8)/(2) = (2x)/(2)` (division property of equality)

`4 = x`

`x = 4`

8.
`(3)/(x - 3) = (6)/(8)`

Cross multiply

`3*8 = 6(x - 3)`

`24 = 6x - 18`

`24 + 18 = 6x` (addition property of equality)

`42 = 6x`

Divide both sides by 6

`7 = x`

`x = 7`
