Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2

Answer:
Place the decimal before the last digit in both number i.e. 1602.3 and 65.4
Step-by-step explanation:
We are given the numerical expression 16023÷654.
Here, we have,
Dividend = 16023
Divisor = 654
it is required that the quotient of the division to be between 23 and 25.
If we take the numbers,
1602.3 and 65.4
This gives us,
.
Hence, placing the decimal before the last digit in both number will give the desired result.
