Question

Collin solved the inequality:
10x + 7 – 11x < -20
Collin thinks that the solution is 27.
a. Do you agree or disagree with Collin's answer?
b. Clearly explain to Collin why you agree or disagree with his solution. If you disagree, please give the
correct solution
*Be sure to answer BOTH questions!

Answer 1

Step-by-step explanation:

collin is correct and incorrect at the same time. when you solve this, you start with adding like terms.

10x and -11x will be added together to be -1x, after we figure this out, we solve.

-1x+7<-20

-7       -7

-1x<-27

/-1   /-1

x<27

after you solve, you notice that x is less than 27. collin has the correct answer for solving the equation, but if were looking on a more technical note, he would be incorrect because he said the answer is 27, when the answer is actually less than 27. therefore, collin has solved the inequality correctly, but he has said the answer incorrectly
