Some number added to 5 is equal to -11. Find the number.
Some number added to -11 is 37. Divide this number by -12. Then, multiply by -8. What is the final number?
A friend of mine gave me these, and I'm having a hard time finding the answers.
Thanks in advance!

x + 5 = -11
x = -16
y + (-11) = 37
y = 37 + 11 = 48
48/12 = 4
4 * -8 = -32

Set up an algebraic equation where x equals the number that is added.
X + 5 = -11 Then solve.
X= -16
X + -11 = 37
X = 48
48/(-12) = -4 * -8 = 32

x+5=-11
Subtract 5 and number left is
-16
x+ -11=37
Add 11 to both sides and the number is
48
48/-12= -4
-4 X -8=32

Let x = some number
x + 5 = -11
x = -16
The number is -16
x + -11 = 37
x = 48
48/-12 = -4
-4*-8 = 32
The final number is 32

-16 and 32
-11 -5 = -16
48+-11 = 37
48/-12 = -4
-4 * -8 = 32

5 + x = -11
5 - 5 + x = -11 - 5
x = -16
-11 + x = 37
x = 48
x / -12 = -4
-4 * -8 = 32

-16 + 5 = -11 ; you were looking for -16
48 + (-11) = 37 ; you were looking for 48
48 / (-12) = -4
(-4) * (-8) = 32

let x be the number.
x+5=-11 subtract 5 from each side
x=-16
x-11=37 add 11 to each side
x=48
48/-12*-8=72
