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 1150. If three times the number of one-step equations minus twice the number of two-step equations is equal to 1300, how many one-step equations auditioned today?

Question

anonymous · Answer

put x = number of one step equations, then 1150 - x equal number of two step equations (since their total is 1150
then solve 
$$3x-2(1150-x)=1300$$for x

anonymous · Answer

$$3x-2300+2x=1300$$
$$5x-2300=1300$$
$$5x=3600$$
$$x=720$$
