Question

Can y'all help me with these too please

Answer 1

Answer:

6. Z= -11

7. N= 15.25

Step-by-step explanation:

6. Subtract 10 from each side to get Z+3= -8

Then Subtract 3 from each side to get Z= -11

7. Subtract 4 from each side to get 3/4 n= 16

Then Subtract 3/4 to get N= 15.25

Answer 2

z + 3/10 = 2

z+3 = 2 × 10

z +3 = 20

z = 20-3

z = 17

(3/4)n + 4 = 20

n + 4 = 20 ÷ 3/4

n + 4 = 20 × 4/3

n + 4 = 80/3

n = 80/3 -4

n = 80-12/3

n = 68/3
