Answer:
d. 18
Step-by-step explanation:
3x - 5 = 22
3x = 27
x = 9
Then, 2x is equal to:
= 2(9)
= 18
You can rewrite the second equation because you know what y equals, so you can write it as 2x + x + 3 = 9
3x + 3 = 9
- 3
3x = 6
÷ 3
x = 2
And now you use the equation of what y equals and substitute in the value of x, so y = 2 + 3
y = 5
So your final answer is A. (2, 5). I hope this helps!
A
x=y^2-9
x+9=y^2
square root both sides
+-sqrt(x+9)
