Question

The expressions a(8x+7) and 4x+3.5 are equivalent. What is the value of a?

Answer 1

a=1/2

Explanation:

From the question, the expression a(8x+7) is equivalent to 4x+3.5

Which means that multiplying 8x by a gives 4x and multiplying 7 by a gives 3.5

So, we can write the following to find the value of a

`a(8x+7)\equiv 4x+3.5`

we can write the following

8ax=4x

`\implies a=(4x)/(8x)= (1)/(2)`

Hence the value of a is 1/2
