You need to isolate either X or Y
For the first problem I decided to isolate the X
I moved the Y and -2 over to the other side of the equal sign. this makes their positive or negative values to turn the opposite. Heres how this looks
5x=-3y-4+2
I then add both the 2 and -4 together to get -2. this is how that would look like
5x=-3y-2
I now have to divide everything by 5 so i can have X by itself. this is what X equals
5/5X= -3/5y-2/5
x=-3/5y-2/5
Now we go back to the problem but we implement the bolded instead of there being an X. This is how that would look like
5(-3/5y-2/5)+3y-2=-4
then I multiply the bolded by 5.
-3y-2+3y-2=-4
from here I just add
-4=-4
I then go back to the original problem and implement the -4 into the Y
5x+3(-4)-2=-4
Solve for x
5x-12-2=-4
5x-14=-4
5x=10
from here we isolate the x by dividing by 5
5/5x=10/5
this leaves us with
x=2
y=-4
To check our answer we imput those into their correct positions. this is how it would look like
5(2)+3(-4)-2=-4
10-12-2=-4
10-14=-4
-4=-4
When both equal the same we know this is True and with that we know the answers are correct. Ill let you try the other 2 so you can get some practice in. (ps. they are easier than the first one)
HOPE THIS HELPED. DONT FORGET TO PUT THIS AS THE BRAINLIEST ANSWER, GIVE IT A 5 STAR AND A HEART.
