Hey there!!
Given equation :
( x - 1 ) / 4 = ( x + 2 ) / 3
First step we will need to take is to cross-multiply. In cross-multiplication, we will have t multiply the denominator with the numerator on both the sides. In this case, we will have to multiply 4 with x + 2 and 3 with x - 1.
... 4 ( x + 2 ) = 3 ( x - 1 )
... 4x + 8 = 3x - 3
Subtract 3x on both sides.
... x + 8 = -3
Subtract 8 on both sides
... x = - 11
Hope my answer helps!

Answer:
○ Subtract 8 from both sides, then divide both sides by 1/3
Step-by-step explanation:
Perhaps the usual sequence of steps is ...
add 8:
3y = 27
divide by 3 (equivalently, multiply by 1/3)
y = 9
___
If the division by 3 is done first, then the constant on the left becomes -8/3, so cancelling it requires adding 8/3 to both sides of the equation.
_____
If you do the last suggestion, you get ...
subtract 8 from both sides:
-16 +3y = 11
divide both sides by 1/3:
-48 +9y = 33 . . . . . . . does not solve the equation completely
