Answer:
x - y = -1 ....... 1
3x + 2y = 22 ........ 2
Make x the subject in the first equation
x = -1+y
Substitute this into the second equation
3(-1+y) + 2y = 22
-3 + 3y + 2y = 22
5y = 25
Divide both sides by 5
y = 5
Substitute y = 5 into x = -1+y
x = -1+5
x = 4
x = 4 , y = 5
Hope this helps
Answer:
168 unlimited-ride passes.
Step-by-step explanation:
50x+20y=10680
x+y=282
Multiply.
20(x+y=282)
20x+20y=5640
Subtract.
50x-20x+20y-20y=10680-5640.
30x=5040
x=168
Hope this helps plz hit the crown :D
Answer
B
explanation
get the difference between the y valuesand divide it by the difference between the x values
let the original price be x.
then,
x- 25% of x= 24
x- 25x/100 = 24
x- x/4=24
3x/4=24
3x= 96
x= 32
in short...the original price= 32 dollars
I'm assuming that the line is JKL in order of the points from left to right.
JK + KL = JL
(17-x) + (2x-7) = JL
Simplify.
10-x = JL
