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:
1129/200 = 5.645
Step-by-step explanation:
31/8 ÷ (x-4 1/4)=17/18 +1 5/6=17/18 +11/6=17/18 +33/18=(17+33)/18=50/18=25/9
31/8 ÷ (x-4 1/4)=25/9
x-4 1/4 = 31/8 ÷25/9 = 31/8 × 9/25 = 279/200
x = 4 1/4 + 279/200 = 17/4 + 279/200 = 850/200 + 279/200 = 1129/200 = 5.645
Answer: son 24 daughter 12
100= total years of age of all ppl in 4years but we want their age now
100=(52+4)+(2x+4)+(x+4)
3x=36
x=12
So daughter is 12 and son is 2x or 24
