Answer:
(x,y)=(5,-1)
Step-by-step explanation:
1. 2x+y=9 ---> y=9-2x
2. Substitute y=9-2x into 3x-2y=17 ---> 3x-2(9-2x)=17 ---> 3x-18+4x=17 --> 7x=35 ---> x=5.
3. Substitute x=5 into 2x+y=9 ---> 2*5+y=9 ---> y=9-10 ---> y= -1
Answer:
x=14
Step-by-step explanation:
To solve, we need to isolate the variable (x)
3x-6=36
Add 6 to both sides
3x=42
Divide by 3 on both sides
x=14
14 is the value that make the equation true

4 13/20 terminates. When you divide 13 by 20 you get 0.65 which terminates.
Answer:
0
Step-by-step explanation:
Substitute the value of x to the 2nd equation
3(2y-4)-6y=-12
6y-12-6y=-12
0=0
