Answer 1

-3=√b-5

-√b=-5+3

-√b=-2

√b=2

b=4

verification :

-3=√4-5

-3=2-5

-3=-3

Explanation:

Answer 2

Hello!

Answer:

`\Large \boxed{\sf b =4}`

Explanation:

→ We want to solve this equation:

`\sf -3 = √(b) - 5`

◼ Add 5 to both sides:

`\sf -3+5 = √(b) - 5+5`

◼ Simplify both sides:

`\sf 2 = √(b)`

◼ We know that if
`\sf √(x) = a`, then
`\sf x =a^2`:

`\sf 2^2 = √(b)^2`

◼ Simplify both sides:

`\boxed{\sf b =4}`

Conclusion:

The solution of the equation
`\sf -3 = √(b) - 5` is
`\sf 4`.
