Isolate one term (x or y) in one of the equations
6x+6y=0
6x=-6y
X= -1y
Substitute x=-y into the other equation
-7(-y) + 2y =18
7y + 2y =18
9y=18
Y=2
Substitute y=2 into 6x+6y=0
6x + 6(2) = 0
6x + 12=0
6x= -12
X = -2

➷ w + 5 = 13
We need to isolate 'w'
To do that, subtract 5 from both sides
w = 13 - 5
Solve:
w = 8

Answer:
Step-by-step explanation:
The height y of an angled ladder, x ft from its base is given by the formula
To find the formula for x in terms of y, first express ax:
If divide the previous equation by a:
