Use the working backwards method to find the solution of the equation. 4y - 1 = 7

y=2

Step-by-step explanation:

By looking at the given equation

LEts think of

1. a number for y

2. multiply the number by 4

3. subtract 1 from it

4. that is equal to 7

Now we work backwards to solve for the equation for y

we start from 7

Opposite of subtraction is addition, so we add 1 on both sides

Opposite of multiplication is division

so we divide both sides by 4

y=2

So the value of y is 2

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.
