Lemur [1.5K]

<u>Answer:</u>

The correct answer option is C. 1.

<u>Step-by-step explanation:</u>

We are to divide $\frac { 4 0 x } { 6 4 y }$ by $\frac { 5 x } { 8 y }$ .

Rewriting them as a fraction in whole:

$\frac { \frac { 4 0 x } { 6 4 y } } {\frac { 5 x } { 8 y } }$

Changing the division into multiplication by taking the reciprocal of the fraction in the denominator to get:

$\frac { 4 0 x } { 6 4 y }$ × $\frac{8y}{5x}$

Cancelling out the like terms to get:

lara31 [8.8K]

Answer:

x+2a=12+ax-6a

Step-by-step explanation:

collect liked terms:

x+2a=12+ax-6a

2a-ax+6a=12-x

factorize a on the left hand side:

a(2-x+6)=12-x

divide both sides by (2-x+6) :

a(2-x+6)/(2-x+6)= 12-x/(2-x+6)

a= 12-x

____
