we have to solve the system. multiply the 2nd by -3 -9x + 3y = 18 add that to the first -9x + 3y = 18 4x- 3y = -3 -5x = 15 x = -3 sub into the original 2nd -9 - y = -6 9+y=6 y = -3 so they intersect at (-3,-3)

**math**

in this case, substitution is your obvious choice sub the 2nd into the 1st. 2(4y+1) - 3y = 12 8y + 2 - 3y = 12 5y = 10 y = 2 sub into the 2nd x = 4(2) + 1 = 9 x = 9 , y = 2

You have 3 consecutive questions of this type. Why do you want to use 3 variables, it is much easier to just define one, and the use the given to define the others. e.g. let the first number be x then the 2nd number is 3x-6 and the 3rd is (2/3)(3x-6) + 2 = 2x -4 + 2 = 2x - 2 ...
