Answer:
22
Step-by-step explanation:
substitute:
5(7) - 3(8) + 11=0
35 - 24 + 11 = 0
=22
1/ 3x+ 2x-6= 4
-> 5x=10
-> x=2
2/ x=6-y
-> 2.(6-y)-y=6
-> 12-2y-y=6
-> -3y= -6
-> y= 2
Answer:
Step-by-step explanation:
Cost of 4 oranges = $x
cost of 1 orange= x/4
Cost of 10 oranges = x/4*10 = $ 2.5x
Cost of a custard apple = $1.25
Cost of n custard apple = 1.25*n = 1.25n
Cost of 4 bananas = $3
Cost of a banana = 3/4 = $0.75
Cost of (3n +1) bananas = 0.75*(3n+1) = 0.75* 3n + 0.75*1 = 2.25n + 0.75
Cost of fruits = 2.5x + 1.25 n + 2.25n + 0.75
= 2.5x + 3.50n +0.75
4x-3 is the answer that you are looking for! I always distribute the negative one to the second set and then line it up like so:
..7x-5
-3x+2
--------
.4x-3
