Answer:

The expressions a(8x+7) and 4x + 3.5 are equivalent

Therefore, according to the above problem the equation is :---

[tex]a(8x + 7) = (4x + 3.5) \\ 8ax + 7a = 4x + 3.5[/tex]

By comparing the term, we get

[tex]8ax = 4x \\ 8a = 4 \\ a = \frac{4}{8} \\ \boxed{a = \frac{1}{2} }[/tex]

and,

[tex]7a = 3.5 \\ a = \frac{3.5}{7} \\ \boxed{a = \frac{1}{2} }[/tex]

The value of "a" is 1/2.

Answer:

The expressions a(8[tex]x[/tex] + 7) and 4x + 3.5 are equivalent

Step-by-step explanation:

a(8x+7)=4x+3.5

8ax+7a=4x+3.5

let keep a=1/2

8/2x+7/2=4x+3.5

4x+3.5=4x+3.5

so no is or value of a=1.5
