-6 + f = 2 f=8, what are the steps for this?
I assume that you meant -6 + f = 2f - 8
\(-6+f = 2f-8\\ f-6=2f-8\\ f+2=2f\\ 2 =f\\ f=2\)
If you meant:
Does -6 + f = 2 if f = 8 ?
-6 + f \(\stackrel{?}{=}\) 2
Replace " f " with " 8 " .
-6 + 8 \(\stackrel{?}{=}\) 2
Simplify left side of equation.
2 \(\stackrel{?}{=}\) 2
2 = 2 true
Yes, -6 + f = 2 if f = 8 .
