Question

What is the solution to the equation?



2q + 18 = –5q – 3



A.


q = –5


B.


q = –3


C.


q = 3


D.


q = 5

Answer 1

to solve for a variable
you want to try to get the variable alone
the first step would be to get all the terms with the variable to one side
so first add 5q to both sides
then subtract both sides by 18
then divide both sides by 7

Answer 2

It would be 3

Answer 3

when you subtract both sides by 18
you would get a negative 21 on the right, right?

Answer 4

yes

Subtract 18 from -3
2q=-5q-21
Add 5q to 2q
7q=-21
divide -21 by 7
A=-3

Answer 5

yes, that would be correct :)
