X - 2 = -3x +2
what's x?

x = 1

Step-by-step explanation:

x - 2 = -3x + 2

you can do any one of these 4 steps first and still get the same

a) subtract x from each side

b) add 2 to each side

c) add 3x to each side

d) subtract 2 from each side

the answer is y = 11.54

hope this : )

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:
