I would say c but that is just a guess
You can subtract 4x from each side of the equation.
Then you'll have the variable only on one side.
Before: 5x - 7 = 4x - 1
After: x - 7 = - 1
Now it's a lot easier to solve.
========================================
I just noticed that you're giving 10 points for this one.
That's a bunch, so I guess I owe you some more ...
I really ought to go ahead and finish the solution:
Original equation: 5x - 7 = 4x - 1
Subtract 4x from each side: x - 7 = - 1
Add 7 to each side: x = 6
(Once you subtracted 4x from each side,
there really wasn't much more left to do.)
Answer:
It's C
Step-by-step explanation:
So if Aiden earns 22 per hour and Parker 26 per hour too you need to add 22+26 and Aiden had a bonus of $100 so you need to do this 22+26= __ + 100 =
Hope it helps
Answer: The Answer Is C.
Step-by-step explanation:
When you divide each of them you will notice that C costs the least.
For choice A when you 5 by 3.25 you will get 0.65.
For choice B when you divide 8 by 6.10 you will get 0.7625
For choice C when you divide 12 by 7 you will get 0.5833.....
For choice D when you divide 10 by 6.44 you will get 0.644.
So when you look at the results you will see that choice C is the best deal.
3x - y = 6 ------------ (1)
y = x - 4 ------------ (2)
From (1) + (2) :
( 3x - y) + y = 6 + (x - 4)
3x - y + y = 6 + x - 4
3x = x + 2
2x = 2
x = 1 ------------- Sub into (2)
y = x - 4
y = 1 - 4
y = -3
Answer: x = 1, y = -3
