Question

What is the answer and work for -27+5u=-48

Answer 1

u=-4.2

Explanation:

first add 27 to -48

`- 48 + 27 = - 21`

then you need to divide -21 by 5 to get answer

`5u = - 21 \\ - 21 / 5 \\ u = - 4.2`

Answer 2

u = -21/5 = -4.200

Explanation:

Solve : 5u+21 = 0

Subtract 21 from both sides of the equation :

5u = -21

Divide both sides of the equation by 5:

u = -21/5 = -4.200

One solution was found :

u = -21/5 = -4.200
