Question

If Y is equals to X + 3 divided by 12 find the value of x if Y is equals to 5

Answer 1

$y = (x + 3) \div 12$
$y = 5$
$y = (5 + 3) \div 12 = 8 \div 12 = 2 \div 12 = 0.666$

Answer 2

Take y=x+3/12, x+y=5

Substitute y in equation 2

12x+x+3/12=5

13x+3=60

X=57/13

Substitute x in equation 2

57/13+y=5

Y=8/13

Therefore x=57/13, y=8/13
