Ok here it is:
4x-5y=40
2x+10y=20
I used the second equation and decided to get x
2x+10y=20
Subtract 10y from both sides.
2x=-10y+20
Divide both sides by 2
x=-5y+10
Put that in for x for first equation
4(-5y+10)-5y=40
Distribute the 4
-20y+40 -5y =40
Combine like terms
-25y+40=40
Subtract 40 from both sides
-25y=0
Divide by -25 on both sides
y=0
Substitute the y in for the 2nd equation
2x+10(0)=20
2x=20
Divide both sides by 2
x=10
So x=10 and y=0
Answer: I would think
6-0
12-1
30-2
Step-by-step explanation:
Answer:
X-16 the first one
Step-by-step explanation:
The first one is equal to x-4
= 120/100 x 320
= 12 x 32
= 384
It is given that, Shyla had a balance of −$255.25 in her account, and Susan had a balance of −$178.75 in her account.
And absolute value of -255.25 =255.25 which is greater than absolute value of -178.75 which is 178.75. It means , Shyla's account balance is more than Susan's account balance . THerefore, Shyla owes the bank more than Susan .
