Solve for x



2. -3(x + 5 = -9




3. X+(/2.5= -7.79

Solve for n


4. 3.33 + 2n = -7

Answer 1

Answer: 1. y = 6

2. x = -2

3. X = -10.29

4. n = -5.165

Explanation:

1. -2y + 7 = -5

-2y + 7 - 7 = -5 - 7

-2y = -12

y = 6

2.-3(x + 5) = -9

3(x+5) = 9

x+5 = 3

x = 3 - 5

x = -2

3. X+2.5= -7.79

X= -7.79 - 2.50

X = -10.29

4. 3.33 + 2n = -7

3.33 - 3.33 + 2n = -7 - 3.33

2n = -10.33

n = -5.165
