(a+3)x=(a+3)(a-2) equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
(a+3)*x = (a+3)*(a-2)
Expand brackets in the left part
a+3x = (a+3)*(a-2)
Expand brackets in the right part
a+3x = a+3a-2
Looking for similar summands in the left part:
x*(3 + a) = a+3a-2
Looking for similar summands in the right part:
x*(3 + a) = (-2 + a)*(3 + a)
Divide both parts of the equation by 3 + a
x = (-2 + a)*(3 + a) / (3 + a)
We get the answer: x = -2 + a
