DUE TODAY (10/11/22) Need help on two questions!!

What term would you move using inverse operations to put this equation into standard form (Ax+By=C)

3x = 5 - 2y


5 by subtracting 5 to the other side

3x by dividing by 3 on both sides

-2y by adding 2y to other side


Natalie wanted to find the y intercept for the standard form of this equation. Here are her steps. Did Natalie make a mistake? If so, which one was her first? If not, indicate that as well.

Solve for the y intercept by substituting 0 for x.

2x + 4y = 20


Step 1: 2(0) + 4y = 20

Step 2: 0 + 4y = 20

Step 3: 4*4y = 20 * 4

Step 4: y = 80


A: Step 1

B: Step 2

C: Step 3

D: Step 4

E: Natalie made no mistakes

#1) -2y by adding 2y to other side

#2) C: Step 3

Step-by-step explanation:

#1) 5 is the only number without a variable, so isolating it would make the standard form true.

#2) Opposite of multiplication is division, so rather than multiplying 4 to both sides, Natalie should've divided.
