Answer:
B and E
aka
E-F and E-D
C-B and C-D
Step-by-step explanation:
2)
4x-10y=12
Subtract 4x from each side.
-10y=-4x+12
Divide both sides by -10
y=2/5x-6/5
3)
13=1/6y+2x
Subtract 2x from each side.
-2x+13=1/6y
Multiply both sides by 6.
-12x+78=y
Flip it around.
y=-12x+78
Hope this helps!
"Over" usually means divide. First hint, check.
If we write it out, it looks like this:
This is the same as <em>some number divided by 7.</em>
