Answer:
The x-coordinate of the solution is x=3
Step-by-step explanation:
we have
------> equation A
------> equation B
Solve the system of equations by substitution
Substitute equation B in equation A and solve for x
Find the value of y
------>
The solution of the system of equations is the point (3,2)
therefore
The x-coordinate of the solution is x=3
we have
Solve for c--------> that means that clear variable c
so
Divide by both sides
Adds both sides
Multiply by both sides
so
therefore
<u>the answer is</u>
