Problema Solution

Five times the sum of a number and ten is ten. Find the number

Answer provided by our tutors

Set up the equation:

5 (x+10) = 10

Divide both sides by 5:

[5(x+10)]/5 = 10/5

x+10 = 2

Subtract 10 from both sides:

x+10-10 = 2-10

x = -8

 

Checking:

5 (-8+10)

5 (2)

=10

 

Therefore, x = -8
