Question

-2(2x-___)+ 1 = 17- 4x

c. For what missing value(s), if any, does the equation have no solution?

Answer 1

The answer is -8, it has a solution

Answer 2

Let missing place be y

• Solution has no solution means both sides are equal

`-2(2x-y)+1=17-4x`

`\\ \sf\longmapsto -4x+2y+1=17-4x`

`\\ \sf\longmapsto 17-4x=2y+1-4x`

On comparing

`\\ \sf\longmapsto 2y+1=17`

`\\ \sf\longmapsto 2y=17-1`

`\\ \sf\longmapsto 2y=16`

`\\ \sf\longmapsto y=(16)/(2)`

`\\ \sf\longmapsto y=8`
