Answer: Choice B)
2x+5(2x+3) = 3
============================================
Reasoning:
We start with the second equation 2x+5y = 3
Since y = 2x+3 from the first equation, we can replace every copy of y with (2x+3). This replacement is valid because y and 2x+3 are the same.
So that's how we go from 2x+5y = 3 to 2x+5(2x+3) = 3
This replacement is done to get rid of the y variable, and it allows us to solve for x later on.
Step-by-step explanation:
When x = -2, x + 2 = (-2) + 2 = 0.
400+30+7. +0+4
3,000,000+500+40+3,000+2+1
The answer is 1 and 4/5. Just divide and put the remainder as the numerator and the numerator stays the same
