Answer:
(-1,3)
Step-by-step explanation:
Solve for x in the first equation
3x = 6 - 3y
9x - 5y= -24
Replace all occurrences of x with 2 - y in each equation
9(2 - y) - 5y = -24
x = 2 - y
Simplify the left side
18 - 4y = -24
x = 2 - y
Solve for y in the first equation
-14y = -42
x = 2 - y
y=3
x = 2- y
Replace all occurrences of y with 3 in each equation
x=-1
y=3
(-1,3)

The first answer, the Data is the same as the answer
1. "the sum of -4x and 2 is 9"? -4x + 2 = 9
Answer:
A.-4x + 2 = 9
2. solve x - 6 = -18
x = -18 +6
x = -12
Answer is B.x = -12
3. solve 4x + 3 = 47
4x = 47 -3
4x = 44
x = 44/44 = 11
Answer is A.x = 11
4. solve 1/3x = 12
x= 12 / (1/3)
x = 12 * 3 = 36
Answer is C.x = 36
5. solve 3x + 3 = 21
3x = 21 -3
3x = 18
x = 18/3 = 6
Answer is B.x = 6
6. solve. 3/2x - 4 = 16
3/2x = 16 + 4
3/2x =20
x = 20 / (3/2)
x = 20 * 2/3
x = 40/3
A.x = 13 1/3
Answer is B.x = 13 1/3
