Answer:
x is the reciprocal of the difference of a and b.
Step-by-step explanation:
ax=bx+1
Subtract by bx on both sides
ax-bx=1
x(a-b)=1
x= 1/(a-b)
1 hour and 30 minutes because when you subtract those you will get that answer
I worked them out on paper. I hope this helps. There’s a picture of the work.
The given matrix represent the following linear system
4x - 7y = -12
-14x + 4y = 4
Good luck!!!
You need an equation system.
First, translate the text into equations :
y = total price for the bike
x = number of months
first bike :
y = 25x + 500
second bike :
y = 50x + 200
Then you have to solve the system by placing the two equations side by side and comparing them.
25x + 500 = 50x + 200
Solve to find the value of x
