Solve for x. 7x + 9 = 6x - 5 x = -4 x = -14 x = 4 x = 14

x=-14

Step-by-step explanation:

7x+9=6x-5

1) Start by subtracting 9 from both sides:

7x=6x-14

2) Now subtract 6x from both sides:

x=-14

Footnotes:

1) Whatever you do to one side you must also do to the other

2) The goal is to isolate or get the variable "x" alone on one side.

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.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

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