Answer:
6x-5y=4
6x+3y=30
Step-by-step explanation:
Move variable to the left
5y=6x-4
Reorder the terms
5y-6x=-4
Change the signs
-6x+5y=-4
Move variable to the left
3y=-6x+20
Reorder the terms
3y+6x=20
solve for x.
4x−5=7+4y
Add 5 to both sides.
4x−5+5=4y+7+5
4x=4y+12
Divide both sides by 4.
4x/4=4y+12/4
x=y+3
