Answer:
The x-coordinate of the solution is x=3
Step-by-step explanation:
we have
 ------> equation A
 ------> equation A
 ------> equation B
 ------> 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
