<h3>How to solve the simultaneous equation?</h3>
Given:
x-y=k.............(eq i)
2x²+y²-15..............(eq ii)
We would make y the subject formula in eq ii
2x²+y²-15= 0
2x² + y²= 15
y²= 15-2x²
y= ...........(eq iii)
Substitute the value of y into eq i
x-(= k
x- (= k
k=

Answer/Step-by-step explanation:
To solve the given expression, , the following steps as well as justification for each step is given below:
Step 1: state the given expression
(given)
Step 2: solve for x by subtracting 12.7 from each side of the equation.
Step 3: Apply the additive inverse rule and simplify (i.e the additive inverse of 12.7 is -12.7. when added, it gives us 0)
(additive inverse/simplification)
Step 4: additive identity rule (i.e. the 0 added to x = 0)
(identity property of addition)
