Answer:
Multiply the first equation by -4
Step-by-step explanation:
Equation A: 3c = d − 8
Equation B: c = 4d + 8
We want to eliminate variable d
Multiply the first equation by -4
-4( 3c = d − 8)
-12c = -4d +32
Add this to the second equation
-12c = -4d +32
c = 4d + 8
================
-11c = 0d + 40
Answer:
1/16
Events A+B are written (P) yellow : 1/4 * (P) green : 1/4
Ao event = (P) 1/4 * 1/4 = 1/16

Answer:
x=-1
Step-by-step explanation:
5x+3=-2
subtract 3 from both sides
5x=-2-3
Subtract 3 from -2 to get -5
5x=-5
Divide by 5 on both sides
x=-5/5
Divide -5 by 5 to get -1
x=-1
