Description
how do you work this problem
-2(x +6)+3(2x-5)=3(x-4)+10
Explanation & Answer
Thank you for the opportunity to help you with your question!
To solve this problem, you first need to distribute the outer numbers to the inner numbers of the parentheses. A general formula for this principle would look like this: a(b+c)=a*b+a*c. Be careful with the positives and negatives though. Another general formula: a(b-c)=a*b-a*c. Now when 'a' is negative: -a(b+c)=-a*b-a*c
-2(x+6)+3(2x-5)=3(x-4)+10 Distribute terms.
-2x-12+6x-15=3x-12+10 Now combine 'like' terms.
4x-27=3x-2 Get the 'x' terms on one side to solve for x.
x=25
