Question 245681
Can you help me with this problem? If you can show me the steps by step I think I can help my daughter with her homework. 
y = 5x - 10
y = 3x + 8
--------------------
Since both 5x-10 and 3x+8 are equal to "y", they must be 
equal to each other.  That gives you an equation with one
variable.
-------------------------
Equation:
5x-10= 3x+8
Subtract 3x from both sides to get:
2x-10 = 8
Add 10 to both sides to get:
2x = 18
Divide both sides by 2 to solve for "x":
x = 9
------
Since y = 3x+8, y = 3*2+8, y = 6+8, y=14
--------------------------------------------
Final Solution: (9,14)
