Answer:
(5, 2)
Step-by-step explanation:
Lets substitute y = -x + 7 into 4x-5y=10
Then we can write 4x-5y=10 as 4x-5×(-x+7)=10,
4x-(-5x)-35=10
9x-35=10
9x=45
x=5, therefore, y= -5+7=2
The summation symbol means we use the variable i in the equation from the given range. In this case, we are given with the equation 3 i - 15 and i ranges from 2 to 7. The summation using simply the calculator is equal to -9. The answer to this problem is -9.
