Answer:
First statement is correct.
Step-by-step explanation:
In the first statement,
in the left hand side, 10 has -3 as its power but in the right hand side +3 is the 10's power.
According to 10's power, left hand side < right hand side.
Hence, there is no need to check the other statements.

Answer:
(3, 15 )
Step-by-step explanation:
Given the 2 equations
x + y = 18 → (1)
y = 5x → (2)
Substitute y = 5x into (1)
x + 5x = 18
6x = 18 ( divide both sides by 6 )
x = 3
Substitute x = 3 into (2) for corresponding value of y
y = 5(3) = 15
Solution is (3, 15 )
The coordinates are 8, -3.
