Question

18-2q=4

Answer 1

do i subtract 18 from both sides?

Answer 2

18 - 2q = 4

so you bring 18 to the other side which turns it from a positive number to a negative

so you will get

-2q = 4 - 18

-2q = -14

-q = -7

because we have minus q we need to change both sides to a positive so simply make them both positive

q = 7

Answer 3

yeah you can subtract both sides by 18 and then divide both sides by -2

Answer 4

but I can also do
18-2q=4
take away 18 from both sides, now it becomes
2q=-14
divide by 2 on both sides
q=7

this way is also acceptable,right?

Answer 5

yes right
