Answer:
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 [tex]\boxed{x = -3}&[/tex].
Check:
2 × (-3) = -6 + 3 = -3
7 × (-3) = -21
-21 + -3 = -24
So we are correct.
