-7x+3y=-24+7x-2x+5y
-7x+3y=5x+5y-24
-12x-2y=-24
-7x+3y=-11
-36x-6y=-72
-14x+6y=-22
-50x=-94
Okay well I did something wrong
Which equation are you talking about
I don’t see the pic !
Y=31.2
X=15.6
I rounded both to the nearest tenth place.
Z = 3 (This equation is a given)
z(y) = 12 ( This equation is also given)
3y = 12 (as z = 3, plug 3 into z)
3y/3 = 12/3 (isolate the y by dividing 3 to both sides)
* you divide 3 to both sides because of the equal sign. What you do to one side you do to the other
y = 4 (answer for y)
y + 5 (what you are solving for)
(4) + 5 = 9 (As y = 4, plug in 4 for y in this equation)
y + 5 = 9 (4 + 5 = 9, or addition property)
9 is your answer
hope this helps
