No matter how HARD i try word problems still get me-.- 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 1070! If three times the number of one-step equations minus twice the number of two-step equations is equal to 110, how many one-step equations auditioned today?
okay, we need to write two equations based on the information that is given.
okay
So take the 2nd sentence and turn it into a equation
Let E1=1-step equation Let E2= 2-step equation
E1+E2=1070
okay sorry i had to do something
np
do you understand how i got that equation?
my apologize ill brb
and yes i do
don't worry
great!
back
alright, i want you to say the third sentence out loud and while you do this write down what you are saying on a piece of paper.
see thats the hard part i am not good at writing down what i read unless its language arts. i had a tutor that would come to my house he would write it on the white board and i would still be confused
okay, i will write it out
If three times the number of one-step equations minus twice the number of two-step 3 * E1 - 2* E2 = 110 equations is equal to 110
Does that make sense?
yes
Now you have two equations and two unknowns, solve away and then answer your answer is what you got for E1
what would i need to use to solve it
either substitution or elimination. these are methods of solutions for systems of inequalities
wouldnt i be eliminating ?
Our two equations are: E1+E2=1070 AND 3*E1-2*E2=110
have you done elimination in systems of equations recently?
yes but thats my worst one. it get it but i dont get it
do you get substitution?
not exactly im on the harder parts right now
