The substraction property of equality is the property that states that you can solve the value of an equality by subtracting the value that is adding up to the variable by substracting it from the other side of the equality, an example would be like this:

$x+5=15\\x+5(-5)=15(-5)\\x=10$

By substracting form both sides the value that is along the "x" you get the value of the "x".

Y=-|x-2|<br> Please help me

liq [111]

Answer:

y = -|x-2| (*)

2 cases:

case 1: for x≥2 <=> |x-2| = x-2

(*) <=> y = - (x-2)

<=> y = -x+2

<=> x+y = 2

case 2: for x>2 <=> |x-2| = 2-x

(*) <=> y = -(2-x)

<=> y = x-2

<=> x-y = 2

since there are 2 variables but just one equation, we cannot find the exact values of x and y. Instead, we can find some kind of connection between them.
