Question

Solve simutaneously :

(5/2)+(x/8)=y

11+(y/3)=3x

Answer 1

you have what
y
equals

3 [ 11 + (5/2+x/8) / 3 = 3x ] get rid of denominator 1/3
multiply by reciprocal
33 + 5/2 + x / 8 = 9 x

33 + 5/2 + x/ 8 +(- x/8 ) = 9 x + ( - x/ 8)

[ 33+ 5/2 = 9x - x / 8 ] 2

66 + 5 = 18x - x / 4

264+ 20 = 72x - x

284= 71x

4 = x

Answer 2

ok i think
