Answer:
You can't really determine anything here, as we'd need to know also the value of F(x)! Check again if there misses anything in this question.
Answer:
see below
Step-by-step explanation:
Since 2x appears on the left side of both equations, that term can be eliminated by subtraction, which is what the first choice suggests.
The result will be ...
3y = 7 -4y +5 . . . . . . . . . second equation subtracted from the first
7y = 12 . . . . . . add 4y
y = 12/7 . . . . . . divide by 7
__
However, the fact that 2x is by itself on the left side of the second equation suggest that <em>substitution</em> may also be a good option. Perhaps an equally good first step is to use the expression in the second equation to substitute for 2x in the first:
(4y -5) +3y = 7
Either way, the resulting equation is 2-step.
7y = 12 . . . add 5
y = 12/7 . . . divide by 7
___
The other suggested "first steps" do nothing useful.
