Therefore d. is the correct option
Hence ,
The solution of your problem is shown on the picture.
Answer:
x=2, w=22, v=10
Step-by-step explanation:
Solve equation [1] for the variable x [1] x=(3y+6)
Plug this in or variable x in equation [2]
[2] 2(-3y+6)-y= 10
[2] -7y=-2
// solve equation [2] for the variable y
[2] 7y= 2
[2] y=2/7
By now we know this much
X= -3y+6
Y=2/7
Use the y value to solve for x
X=-3(2/7)+6=36/7
(x,y)=(36,7), (2/7)
Think i got it
E= 75
F= 90
G= 25
