When you multiply a number by 12 and subtract the product from 360, the difference is 216. Find the number.

tresset_1 [31]

The equation will be 12a – 360 = 216. Then the value of the variable a will be 48.

<h3>What is the solution of the equation?</h3>

The solution of the equation means the value of the unknown or variable.

When you multiply a number by 12 and subtract the product from 360, the difference is 216.

Let the number be a.

Then we have the equation

12a – 360 = 216

By solving the equation, we have

12a = 216 + 360

12a = 576

a = 576/12

a = 48

A fruit company delivers its fruit in two types of boxes: large and small. a delivery of 6 large boxes and 5 small boxes has a t

Afina-wow [57]

6 large + 5 small = 127 kg ------------ (1)
2 large + 3 small = 51kg ------------ (2)

<u>(2) x 3 :</u>
6 large + 9 small = 153 ---------------- (2a)

<u>(2a) - (1) :</u>
4 small = 26
1 small = 6.5kg ------------ (sub into equation 1)

6 large + 5 small = 127 kg
6 large + 5(6.5) = 127
6 large + 32.5 = 127
6 large = 127 - 32.5
6 large = 94.5
1 large = 15.75 kg

Answer: The small box weighs 6.5kg and the big box weighs 15.75 kg
