Aload of bricks is twice as heavy as a load of sticks. the total weight of 4 loads of bricks and 4 loads of sticks is 771 kilograms. what is the total weight of 1 load of bricks and 3 loads of sticks

The total weight of 1 load of bricks and 3 loads of sticks :

One variable linear equation is an equation that has a variable and the exponent number is one.

Can be stated in the form:

or  

ax + b = c, where a, b, and c are constants, x is a variable

Whereas the two-variable linear equation is a linear equation that has 2 variables and the exponent is one

Can be stated in the form:

x, y = variable

In the statement of the task:

a load of bricks is twice as heavy as a load of sticks.

If we translate this sentence into equation, :

B = 2S ( B = bricks, S = sticks)  ---> equation 1

the total weight of 4 loads of bricks and 4 loads of sticks is 771 kilograms.

If we translate this sentence into equation, :

4B + 4S = 771 kg ---> equation 2

This equation belongs to One variable linear equation  because there is two variable = B&S and the exponent number is one

The solution is :

we put equation 1 in equation 2, become :

8S + 4S = 771 kg

12S = 771 kg

from equation 1 :

B = 2 x S

B = 2 x 64.25 kg

B =

the total weight of 1 load of bricks and 3 loads of sticks

If we translate this sentence into equation,

B + 3S = ?

we enter the values of B and S from the results of the equation above

= 128.5 kg + 3(62.25 kg)

= 128.5 kg + 192.75 kg

=
