Add e to both sides and subtract 2 from both sides :: v+f-2=e
I think either might be a or b
Set the two equations equal to each other and solve for X
The answer is D! Hope this helps!
this only has a variable on one side
-8 = -9 + b/3
add 9 to both sides
1 = b/3
multiply by 3 to both sides
3 = b
check:
-8 = -9 + 3/3
-8 = -9 +1
-8 =-8
