Answer:
(6.5, 14)
Step-by-step explanation:
(I am assuming you meant to put 4x-3=9 and 2x+6=5)
THIS WILL NOT GET YOU A SOLUTION FOR AN EQUATION JUST INTERCEPTS
move terms to one side:
0=4x-3-9
0=2x+6-5
Simplify and change 0 to y:
y=4x-12
y=2x+1
Substitute one equation for y:
2x+1=4x-12
move constant terms to one side:
2x+13=4x
Subtract 2x from 4x:
2x=13
x=6.5
Solve for y with one equation:
y=4(6.5)-12
y=26-12
y=14
