Question

Solve the following equations.
1) 3n+ 14 = 9n + 8
2) 15 − 3(x− 7) = −24
​

Answer 1

Step-by-step explanation:

1. 3n-9n=8-14

-6n= -6

n=-6÷-6

n=1

2. 15-3x-21= -24

-3x-6= -24

-3x=-24+6

-3x = -18

x= -18/-3

x=6

Answer 2

Step-by-step explanation:

1) 3n+14=9n+8

3n-9n=8-14

-6n=-6

n=-6/-6

n=+1

2)15-3(x-7)=-24

15-3x-21=24

-3x-6=24

-3x=24+6

-3x=30

x=30/-3

x=-10
