Answer:
(x, y) = (34/5, -4/5) = (6.8, -0.8)
Step-by-step explanation:
Subtract the first equation from the second to eliminate x.
Substituting for y in the second equation, we can find x.
The solution is (x, y) = (34/5, -4/5) = (6.8, -0.8).

Answer:
(-5, -4)
Step-by-step explanation:
I got it correct and that is right
Isolate the g
w = 7 - √g
Do the opposite of PEMDAS, first subtract 7 from both sides
w (-7) = -√g + 7 (-7)
w - 7 = -√g
multiply -1 (as -√g is the same as -1√g) to both sides
-1(w - 7) = √g
-1w + 7 = √g
to get rid of the square root, you must square both sides
Note: -1w is the same as -w
Note: you are squaring all the terms on the other side, not just one.
(-w + 7)² = (√g)²
g = (-w + 7)²
g = (-w + 7)(-w + 7) (note, this can be the answer your teacher wants, or g = (-w + 7)² )
Use the FOIL method (First, Outside, Inside, Last)
(-w)(-w) = w²
(-w)(7) = -7w
(7)(-w) = -7w
(7)(7) = 49
g = w² - 7w - 7w + 49
simplify (combine all like terms)
g =w² - 7w - 7w + 49
g = w² - 14w + 49
g = w² - 14w + 49 is your answer
hope this helps
