Can someone please help will mark brainliest and please explain

Answer:
Listen wonder kid........
The question consists of some pairs of linear equations.
In
(a) multiply 2 with x-1..... You will get 2x-2
And multiply 3 with x +2... You will get 3x+6
Fine, now equalize them
2x-2 =3x+6............. Bring 2x to the Right Hand Side (RHS) and take 6 to the Left Hand side (LHS)
.
We do this step because, it's needed to keep the variables and constants together, hence we did it
Now the equation will look like - 2-6=3x-2x
Now its easy..... Its - 8 =x
Hence x = - 8 that is minus 8.
Similarly do the bit
(b) the answer is 5/11......
Do let me know in the comment section if u got further doubts..... U r free to ask even the no. (b)
