Question 4 If 2x + 3 + 7x = – 24, what is the value of x?

x = -3

Step-by-step explanation:

Hi!

Let's go step by step as simple as possible.

2x + 3 + 7x = -24

Now we can add like terms:

9x + 3 = -24

We subtract three:

9x = -27

Divide by nine:

x = -3

Thus, the answer is .

Check:

2 × (-3) = -6 + 3 = -3

7 × (-3) = -21

-21 + -3 = -24

So we are correct.

x=-3

Step-by-step explanation:

2x+7x=9x

-24-3=-27

9x=-27

x=-27/9
