Consider the equation 9 – x = 5. a. Solve the equation by first adding x to both sides. b. Solve the equation by first subtracting 9 from both sides. c. Which approach, (a) or (b), did you prefer? Explain.

a.x=4

b.x=4

c.(b)

Step-by-step explanation:

We are given that

a. First we adding x on both sides we get

Now, subtract 5 on both sides we get

b.

We are subtracting 9 from both sides we get

We can solve equation both approach a and b

But I prefer (b) because in approach (b)

There are only 3 step in which we can get answer but in approach (a) we can get answer in 4 steps .

Hence, I prefer approach (b)

it is x=-4

step-by-step explanation:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
