To find the solution of the system, we can set the two equations equal to each other and solve for x:
9x - 2 = 7x + 3
Subtract 7x from both sides:
2x - 2 = 3
Add 2 to both sides:
2x = 5
Divide both sides by 2:
x = 5/2 or 2.5
Now that we have the value of x, we can substitute it back into either of the original equations to find the value of y. Let's use the first equation:
y = 9(2.5) - 2
y = 22.5 - 2
y = 20.5
So the solution to the system is (x, y) = (2.5, 20.5) or (2 1/2, 20 1/2)
What is the solution of the system?
y=9x-2
y=7x+3
