Answer:
y = -2
x = 5
Step-by-step explanation:
3x - y = 17
-x + y = -7
here we can find the sum of the two equations
2x = 10
x = 5
now we can just plug in the value of x to find y
-(5) + y = -7
y = -2
If you are talking about building blocks, then you would get one 10 and 3 ones, then subtract that from 7 ones and would get 6
In this case, the pattern is the number, in this case, 3, multiplied by the number below it.
See?
