Question

Solve the equation 7n – 2 = 5n + 10 for n.

Answer 1

So move all the bits with n in them to one side and then move all the bits without n in them to the other side

Answer 2

n = 6

Answer 3

I don't want the answer I just want someone to show me how how to work it out please

Answer 4

sure what happens if you add 2 to both sides of the equation

Answer 5

like this \[7n -2 +2 = 5n +10 +2\]

Answer 6

7n-2 = 5n +10
7n-5n -2 = 5n-5n +10
2n -2 = 10
2n -2+2=10+2
2n = 12
2n/2 = 12/2
n = 6
