Question

Does X-9=2(x-3)+12 have a solution

Answer 1

`\\ \sf\longmapsto x-9=2(x-3)+12`

`\\ \sf\longmapsto x-9=2x-6+12`

`\\ \sf\longmapsto x-9=2x+6`

`\\ \sf\longmapsto 2x-x=-9-6`

`\\ \sf\longmapsto x=-15`

Answer 2

Yes, and the solution is -15.

Explanation:

x - 9 = 2(x - 3) + 12

x - 9 = 2x - 6 + 12

x = - 15
