Answer:
1. x = -7
2. y = -1
Step-by-step explanation:
1.
-3x - 5 = 16 add 5 to both sides
-3x = 21 divide -3 to both sides
x = -7
2.
-4(y-2) = 12 distribute -4
-4y + 8 = 12 subtract 8 from both sides
-4y = 4 divide -4 to both sides
y = -1

1. x = 9
2. y = -3
The first thing you would do is simplify the inside of the parenthesis to 55/6 using PEMDAS. Next all you do is multiply that by 5 to get 275/6 or 45.833 (repeating) in decimal form.
Answer:
D
B
Step-by-step explanation:
1. x² - 5x = 14
x² -5x -14 = 0
x² +2x -7x -14 = 0
x(x + 2) -7(x + 2) = 0
x - 7 or x + 2 = 0
x = 7 or x = -2
2. y² + 6y + 9 = 49
y² + 6y +9 -49 = 0
y² +6y -40 = 0
y² +10y -4y -40 = 0
y(y + 10) -4(y + 10) = 0
y -4 or y + 10 = 0
y = 4 or y = -10
