First, move the -9y to the other side of the equation by adding 9y to each side:
-7x – 9y +9y = -45 + 9y
So, you have:
-7x = -45 + 9y
Then, divide each side by -7 to get x by itself:
-7x / -7 = (-45 / -7) + (9y / -7)
So the final answer is:
x = 45/7 – 9y/7
Hope this helps:)

-7x – 9y= -45
=>-7x=9y-45
=>-7x=9(y-5)
=>x= -9/7(y-5)

-7x – 9y = -45
transpose -9y to theother side
-7x = -45 + 9y
then divide both sides by – 7
x = (-45 + 9y)/-7
that’s it

-7x-9y=-45
—————————–
-7x=-45+9y
x=(-45+9y)/-7
x=6 3/4 +(-1 2/7)y
