X + (-11) = -18
X =
Answer here
I

We add 11 to each side to get rid of -11 so x = -18 + 11 = -7.

x = -7

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

Add 11 to both sides:

x + (-11) = -18

x - 11 = -18

x - 11 (+11) = -18 (+11)

x = -18 + 11

Simplify. Combine like terms:

x = -18 + 11

x = -7

x = -7 is your answer.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
