If 8q + 2r = 2q + 4, what is r in terms of q ?

8q+2r=2q+4
Move 8q to the other side
2r= 2q+4+(-8q)
2r= 2q-8q+4
2r= -6q+4
(2r= -6q+4)/2
r=-3q+2
This is the most you can simplify this equation.

Hope this helps!

Remember you can do anything to an equation as long as you do it to both sides
in this question, we want to solve for r

minus 8q both sides

8q-8q+2r=2q-8q+4
0+2r=-6q+4
2r=4-6q
divide both sides by 2
(2r)/2=(4-6q)/2
r(2/2)=(4/2)+(-6q/2)
r(1)=2+(-3q)
r=2-3q

Look i don’t know the answer to this but someone else will so just wait a little bit longer
