Answer:
x= -11;y= -19
Step-by-step explanation:
lets name y-2x=3 "A" ;
name 3x-2y=5 "B".
2A: 2y-4x=6
2A+B: (2y-4x)+(3x-2y)=6+5
2y-4x+3x-2y=11
-x=11
so x= -11
so A is : y-2 (-11)=3
y+22=3
so
y= -19
Answer:
your answer is 11 feet, or 132 inches.
Step-by-step explanation:
one bracelet needs 22 inches, but he's making six, so multiply.
you should get 132, which can be divided by 12 to see how many feet you need, since this is what the question requires.

Answer:
(12-7x)
Step-by-step explanation:
144 − 49x²
by observation, we can see that 144 = 12² and 49 = 7²
hence we can rewrite the equation
144 − 49x²
= 12² - 7²x²
= 12² - (7x)²
recall that the expression x² - y² = (x+y)(x-y)
hence,
12² - (7x)²
= (12 + 7x)(12-7x)
(12-7x) appears in the expression above, hence 12 -7x is a factor
