For 1 multiply both sides by 3 which gives you 3y-y=12. Then combine like terms 2y=12. Lastly divide both sides by 2 and you get y=6. And for 3 first multiply both sides by 4 which gives you 6y-32=y+8. After that combine like terms 6y-y-32=8. Now add the equation together 5y=40 and then divide by 5 and get y=8
Answer:
- 15, - 16
Step-by-step explanation:
-15 + (-16) = - 15 - 16 = - 31
x3[x+4y=1]
-
3x+5y=10
-1y=-9
x-1 [-1y=-9]
y=9
I believe it is 2, not 100 percent sure but I think its right
-5- is the correct answer
