Answer:
1. x: x= 6−8y/5
y: y=− 5x/8 + 3/4
2. x: x= 4y−9/7
y: y= 7x+9/4
Explanation and Step:
[8y+5x-6=0]
* Subtract 5x from both sides. Anything subtracted from zero gives its negation.
* Add 6 to both sides.
* The equation is in standard form.
* Divide both sides by 8
* Dividing by 8 undoes the multiplication by 8.
* Divide −5x+6 by 8

[y=7x/4+9/4]
* Since 7x/4 and 9/4 have the same denominator, add them by adding their numerators.
* Divide each term of 7x+9 by 4 to get 7/4 x + 9/4.
