Answer:

x = -2, y = -2

Step-by-step explanation:

Your goal is to try and cancel out a variable. I want to get rid of y so i subtracted the first equation from the second one.

After that I solve for x and got x=-2.

I used x=-2 and plugged it back into either of the equation to solve for y.

timofeeve [1]

Answer:

l =10 units, 9.7 units, 5.5 units

√100 =√l^2

l=10 units

95=l^2

√95 = √l^2

l= 9.7 units

30=l^2

√30=√l^2

l= 5.5 units
