x=-7
Step-by-step explanation:
you bring the 5 to the right and them divide them and divide by 2 both sides which equales to 7
Answer:
no
Step-by-step explanation:
If this were a right triangle we would assume the Pythagorean Theorem to prove it


this gives us
49+64=84.64
this is 143=84.64 and therefore not equal and not a right triangle
<u>x + 5y = 4v</u>
Subtract 5y from each
side of your equation: <em> x = 4v - 5y</em>
