9t-7/3t+5 = 3t-4 / t+6
solve equation plz
Answers
Answer:
(9t-7)(t+6)=(3t+5)(3t-4)
We move all terms to the left:
(9t-7)(t+6)-((3t+5)(3t-4))=0
We multiply parentheses ..
(+9t^2+54t-7t-42)-((3t+5)(3t-4))=0
We calculate terms in parentheses: -((3t+5)(3t-4)), so:
(3t+5)(3t-4)
We multiply parentheses ..
(+9t^2-12t+15t-20)
We get rid of parentheses
9t^2-12t+15t-20
We add all the numbers together, and all the variables
9t^2+3t-20
Back to the equation:
-(9t^2+3t-20)
We get rid of parentheses
9t^2-9t^2+54t-7t-3t-42+20=0
We add all the numbers together, and all the variables
44t-22=0
We move all terms containing t to the left, all other terms to the right
44t=22
t=22/44
t=1/2
