Question

What is the solution for this equation?

by – 12) = 21
O {9, 33)
O {-9, 33}
O {-33, -9}
O {-33, 9}

Answer 1

Sol-1

`\\ \sf\longmapsto |y-12|=21`

`\\ \sf\longmapsto y+12=21`

`\\ \sf\longmapsto y=21-12`

`\\ \sf\longmapsto y=9`

Sol:-2

`\\ \sf\longmapsto y-12=21`

`\\ \sf\longmapsto y=21+12`

`\\ \sf\longmapsto y=33`
