Answer:
Step-by-step explanation:
y = 4 + 3x
3x + 4 = y
- 4 - 4
3x = y - 4
/ 3 / 3
x = 1/3y - 4/3
Answer:

Let's start by breaking down the problem.
This is how it should look. ↓
÷
⇒
⇒ 
What does that <em>x</em> mean? <em>x</em> is just a substituted value for the first 2 equations.
Now, we can solve.
÷

Add 3

Now, multiply 6 times 5 squared. What does 5 squared mean? 5 squared is just 5 times itself once. You most likely want to solve 5 squared before multiplying.

And now for the last step, multiply 25 times 6

With that information, the problem is solved! Your answer is 150
