3/4 = 18/n

1/4 = 6/n

n = 4 × 6

n = 24

1/2:
$\frac{ \frac{1}{2} }{ \frac{4}{2} }$

Or we could expess one of the numbers as a fraction:

Systems of equations pls help!

timama [110]

Equation 1 + equation 2

3x-8y +(-3x+10y) = 9+(-15)
2y= -6
then y=-3

from equation 1
3x-8y=9
3x-8(-3)=9
3x+24=9
3x=9-24=-15
then x=-5
