The three Math Idol judges have been eliminating contestants all day! The number of one-step equations and two-step equations who have been eliminated today is equal to 1120. If three times the number of one-step equations minus twice the number of two-step equations is equal to 1300, how many two-step equations eliminated today?

Oh wait could be B
D looks viable...
this looks like algebra. start with
number of one-step equations = x (give the number of 1-step questions a "name")
number of two-step equations = y
It says the # of 1 step plus # of 2 step add up to equal to 1120.
you would say x+y= 1120
If three times the number of one-step equations minus twice the number of two-step equations is equal to 1300,
three times the number of one-step equations
3 * x or just 3x
minus means - so you now have 3x -
twice the number of two-step
2 * y or 2y
you now have: 3x - 2y
is equal to 1300,
3x-2y = 1300
you have 2 equations and 2 unknowns
3x-2y = 1300
how many two-step equations eliminated today?
they want you to solve for y
So those are the two equations i have to do to find y?
