Question

Tell whether b=11 is a solution of -3=8-b .

Answer 1

Look Below ↓↓↓

Explanation:

Let's solve it and see if it is:-

`\bf -3=8-b`

Simplify both sides of the equation:-

`\bf -3=8-b`

`\bf -3=8+-b`

`\bf -3=-b+8`

Flip the equation:-

`\bf -b+8=-3`

Subtract 8 from both sides:-

`\bf -b+8-8=-3-8`

`\bf -b=-11`

Divide both sides by -1:-

`\bf \cfrac{-b}{-1}=\cfrac{-11}{-1}`

`\bf b=11`

Therefore, yes b = 11!!
