If we want to have solutions for the linear equation, the value of A must be 4,
Which number should go in the box?
Let's define A as the number that should be in the box, now we can write the linear equation in the image as:
A*(5x + 6) = 20x + 24
We want to find the value of A, if we divide both sides by 5x + 6 we will get:
A = (20x + 24)/(5x + 6)
The numerator can be rewritten as:
20x + 24 = 4*(5x + 6), replacing that we will get:
A = 4*(5x + 6)/(5x + 6) = 4
Then we conclude that, if we want to have solutions for the linear equation, the value of A must be 4.
