Respuesta :

we will do factor 3/4 out of 3/4z + 6

we have 3/4 z+6= 3/4 z+ 3/4x8= 3/4(z+8)

we have done
Have a good day
ANSWER

[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 8 )[/tex]


EXPLANATION

We want to factor
[tex] \frac{3}{4} [/tex]
out of

[tex] \frac{3}{4} z + 6[/tex]

The first term is already having a factor of
[tex] \frac{3}{4} [/tex]
The constant term which is the second term is not having a factor of
[tex] \frac{3}{4} [/tex]
so we need to use a trick of multiplying and dividing by the same factor to obtain,



[tex] \frac{3}{4} z + 6 = \frac{3}{4} z + \frac{3}{4} \times \frac{6}{ \frac{3}{4} } [/tex]


We can now factor
[tex] \frac{3}{4} [/tex]
out of the right hand side to obtain,

[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + \frac{6}{ \frac{3}{4} } )[/tex]
Let us rewrite the right most fraction using the normal division symbol.

[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 6 \div \frac{3}{4} )[/tex]




We simplify to obtain,

[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 6 \times \frac{4}{3} )[/tex]



This further gives us,


[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 2 \times 4 )[/tex]



[tex] \frac{3}{4} z + 6 = \frac{3}{4} (z + 8 )[/tex]
