# Solving systems of inequalities word problem

Given a system of linear inequalities that models a context about making chairs and tables, Sal finds how many can be made.

## Want to join the conversation?

• Can two-variable linear inequalities (if you have two of them) be solved like systems of equations, with substitution and elimination, instead of just using the graphing method?
• I do not think so, when doing systems of equations we are just solving for the coordinates where both of the lines crosses. In systems of inequalities we solve for the area that results for overlaping the two inequalities. I might be wrong, so iam waiting for the answer aswell.
• Don't mass produce chairs it causes inflation
• So this is how I'm going to use this in real life huh
• Did you guys change the video paying thing from youtube to your own or something. When I click space to pause, it pauses then plays again, if I hold for 2 seconds, then it pauses(sometimes)
• r u using chromebooks, it doesn't work that well on chromebooks, use mac
• How do you write a real world word problem for inequalities
• Say you have s grams of sugar and f grams of flower and you can make 1 batch of cookies for x and one batch of cupcakes for y how many of each can you make if you want to use up as much as you can?

• When a third of unknown number is added to two, the result is not greater than the number subtracted from one. Find the range of values of the number
• Amended via comment
1/3 x + 2 ≤ 1 - x, add x and -2 to get 4/3x ≤ -1, multiply by reciprocal to get x ≤ - 3/4.
• how do you demonstrate that both x and y can not be negative numbers in any given problem using inequalities?
• I didn't understand the nails part
• I found the zeroes and got a different answer. I got that she was short on boards, not nails. Maximum 8 tables for 150 nails. Am I right?
