Solve the equation -6 + 6n = 42 for n

8

Step-by-step explanation:

-6 + 6n = 42

First move the 6 over to the other side by adding

6n = 48

now you will divide by 6 to get n by itself

n = 8

i think its doubled. let me know

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
