Within the image you will notice the vehicles or VW Beetles in numerous colours representing sure numbers. Are you able to resolve the equations and discover the worth of the lacking quantity?

Test reply bellow:

Allow us to symbolize the vehicles with letters to make it straightforward to resolve.

Let’s us assume the next;

B = Blue automobile

R = Pink Automotive &

G = Inexperienced automobile.

So we are able to convert the equations as;

B + B + B = 18 —-(1)

R + R + R = 9 —-(2)

G x G – G = 6 —-(3)

B X R – G = ? —-(4)

From (1)

B + B + B = 18

3B = 18

Subsequently;

B = 6

From (2)

R + R + R = 9

3R = 9

Subsequently;

R = 3

From (3)

In case of (3) you should use the trial and error technique to get the worth of G;

I may work out 2 numbers that may take the worth of G within the equation.

G could be Three or -2

So let’s put each the values within the equation (4) and discover the worth of the lacking quantity.

B X R – G = ?

6 X 3 – 3 = 18 – 3 = 15

&

6 x 3 -(-2) = 18 + 2 = 20

So the two attainable solutions are 15, 20.
