The solutions of the equation 3x - y = 1 are (-2,-7),(-1,-4) and (3,8) thus option (A),(B) and (D) are correct.
<h3>What is the equation?</h3>
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
As per the given equation,
3x - y = 1
Substitute, x = -2
3(-2) - y = 1
y = -7 thus (-2,-7) satisfied.
Similarly (-1,-4) and (3,8) are also satisfied.
Hence "The solutions of the equation 3x - y = 1 are (-2,-7),(-1,-4) and (3,8)".

Answer:
A) R = P/I²
Step-by-step explanation:
I = √P/R
Square each side
I^2 = (√P/R)^2
I^2 = P/R
Multiply each side by R
I^2R =P/R * R
I^2R = P
Divide by I^2
I^2R / I^2 = P/ I^2
R = P/ I^2
