Answer:

For x=2

Step-by-step explanation:

This problem reduces to solving the equation

4(5x-8)=2(4-x)+4

we expand both sides

20x-32=8-2x+4

rearrange and solve for x:

22x=8+4+32

22x=44

\boxed{x=2}

which is our answer.

What is four over nine equal A over 45
QveST [7]
Answer: A = 20


How to Solve:

Just by looking at this problem I can tell that the denominators (9 an 45) are factors of 9. So the second equation is multiplied by 5 from the first equation.

4/9 x 5

4 x 5 = 20
— -—
9 x 5 = 45

So A would be 20.


Another way to solve this would be by multiplying the 1st equations numerator with the second equations denominator:

4 x 45 = 180

Then divide 180 with the 1st equation’s denominator.

180 / 9 = 20

A = 20
