3x = -5y -------------- (1)
6x - 7y = 17 --------- (2)
From (1):
3x = -5y
x = -5/3 y ---------- sub into (2)
6 (-5/3 y) - 7y = 17
-10y - 7y = 17
-17y = 17
y = -1 ------------ Sub into (1)
3x = -5 (-1)
3x = 5
x = 5/3
Ans: x = 5/3, y = -1
Answer:
y = -6x + 3
Step-by-step explanation:
y = -3(2x) -3(-1) = -6x + 3(1) = -6x + 3

Answer:
Step-by-step explanation:
Let n represent the number of necklaces Rosaria ordered. Then the total cost of the order is ...
10(120 -n) +11(n) = 1270
n = 70 . . . . . . . . . . . . . simplify, subtract 1200
120 -70 = 50 . . . . . . . the number of bracelets
Rosaria purchased 70 necklaces and 50 bracelets.
Answer: He did not convert the fractions into the like fraction to add.
Step-by-step explanation:
Given: The distance Jonah runs on Sunday= 
miles
The distance Jonah runs on Monday= 
miles
The total distance he ran = 
Since both the fractions are not like , thus multiply 2 to the numerator and the denominator of the first fraction [to add fractions first convert them into like fractions], we get
The total distance he ran = 
The right answer is "The total distance he ran =
"
