Question

Given that 2x – 2y = 23

Find & when y = 9
Give your answer as an improper fraction in its simplest form.​

Answer 1

2x-2y=23

2x-18=23

2x=23+18

2x=41

2x/2=41/2

x=20.5

Answer 2

x = 41/2

Explanation:

I am assuming that we are finding 'x' when y = 9.

`2x-2y=23\\\\2x-2(9)=23\\\\2x-18=23\\\\2x-18+18=23+18\\\\2x=41\\\\(2x=41)/(2)\\\\\boxed{x=(41)/(2)}`

Hope this helps!
