8 + _ = 10
10 - 8 = 2
8 + 2 = 10
By solving system by elimination, x= -1 and y=3
Step-by-step explanation:
We need to solve the systems by elimination.
Multiply eq(2) with 4 and subtract eq (1) and eq(2)
Now, multiply eq(1) with 2 and eq(2) with 9 and subtracting both equations:
So, by solving system by elimination, x= -1 and y=3

Step-by-step explanation:
150+30x
1700=150+30x
1550=30x
x=1550/30=51
1. times 2 but make it negative and then times 2 make it postiive.
-512,1024,-2048
2.Follows the same pattern
Answer:
a=5
b=15
Step-by-step explanation:
By following the pattern on the table we can see that the x is increasing by 1 and the y is increasing by 3 each time. Therefore, the next set of numbers would be (5,15).
