Answer:
OPTION F
OPTION D
Step-by-step explanation:
Tom made his first mistake in Step 4, by subtracting 2.
After Step 3, he should have added 2 on both sides i.e.,
x = 4y - 2 should have become x + 2 = 4y - 2 + 2
⇒ x + 2 = 4y
So, in order to correct his mistake, he should add 2 on both the sides of the equation.
So,
"double 2"
2(2)
"add 5"
+ 5
Therefore, the whole expression would be:
2(2) + 5
If you wanted to evaluate it, it would come out like this.
4 + 5
