Question

can you please help me to solve this​

Answer 1

Answer:

2( n + 3 ) = - 12

2n+3 = -12

2n = - 12 - 3

2n = -15

n = -15/2

Answer 2

Step-by-step explanation:

1.n+3 = -12÷2. 4.n+6 = -8 ÷ 2

n+3= -6. n+6 = -4

n. = -6-3. n = -4-6

n = -9. n = -10

2.x/5 = -8-(-3). 5. -3x = -155+20

x/5 = -8+3. -3x = -135

x/5 = -5. x = -135 ÷ -3

x. = -5 × 5. x = 45

x. = -25

3. -2×6. = x+2

-12. = x+2

-12-2= x

-13 =x
