Mulitply second equation by 2 and add to first
3y+2z=12
<u>2y-2z=18 +</u>
5y+0z=30
5y=30
divide 5
y=6
sub back
y-z=9
6-z=9
minus 6
-z=3
times -1
z=--3
x=-3
y=6
Answer:
Step-by-step explanation:
Given :
5 ≤ 4x− 1 < 7
the equation could be spitted into 2
1.
ii.
solving them separately , we have
divide through by 4
solving (ii) we have
add 1 to both sides
combining the solutions , we have
Answer:
Student ticket: $12, Adult ticket: $14
Equations: 260=10x+10y, 94=2x+5y
Step-by-step explanation:
Set adult tickets as y
Set student tickets as x
First day: Total made is 260 so set that equal to 10x + 10y
--> 260=10x+10y
Second day: Total made is 94 so set that equal to 2x + 5y
--> 94=2x+5y
I find it easier to have simplified terms so simplify (divide by 2) the first equation to get: 130=5x+5y
All you have to do now is solve for the two variables.
94=2x+5y - (130=5x+5y) --> x=12, y=14
The term of the sequence is eleven 11
