Question

1. 3(n +15)=30

2. X/3 +10=2x

3. X+34=83




​

Answer 1

Step-by-step explanation:

3*n+15=30

=3n+15=30

=3n= 30-15=15

n = 15/3=5

x/3 - 2x =-10

x-2x =-10*3=-30

-x=-30

x=30

x = 83-34

x = 49

Answer 2

Answer:

1) 3(n+15) =30

3n + 45=30

3n = 30-45

n= -15/3

n=- 5

2)x/3 +10=2x

x/3 +10 =2x

x+30/3=2x

x+30=6x

30=6x-x

30 = 5x

30/5=x

6= x

3)x+34=83

x=49
