Answer 1

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!
