Answer:
y=-5
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are equal and bisect each other
so

step 1
Find the value of x
substitute the given values

solve for x
Multiply by 2 both sides


step 2
Find the value of y

we have


substitute

substitute the value of x

So let's add variables according to the ratio:
3n + 2n = <span>£80
5n = </span><span>£80
n = 16
3(16):2(16)
48:32
Tom gets </span>£48, and Jerry gets <span>£32</span>
You divide 1 by 4.76 and you get 0.21 as your main answer
The possible values of x could be -5 and -1 ithink idk
