Answer:
if u substract the equations u get 4x = 1, therefore x = 1/4
Step-by-step explanation:
(8x + y) - (4x + y) = 5 - 4
4x = 1
x = 1/4
130
I don' know my explanation.
20 so the fractions would be 3/4=15/20 and 9/10=18/20
because 4 x 5 = 20 and 10 x 2 = 20
A.)x/8=3/4
x=6
B.)2/5=x/40
x=16
C.)1/8=x/12
x=3/2 or 1.5 or 1 1/2
D.)x/10=12/15
x=8
A.)x/2+x/6=7
x=21/2 or 10.5 or 10 1/2
B.)x/9+2x/2=1/3
x=3/10 or 0.3
