How to figure out that 50x minus 4% equals 9

0.5X-0.25=9
0.5X=9+0.25
0.5X=9.25
X=9.25÷0.5
X=18.5

To solve the equation, 50% x plus 40 equals 80, 50% x minus 8% 3 equals 20% 3

50 percent plus 40 is 80,
50%X=80-40
50%X=40
X=40÷50%
X=80
50x minus 3 percent is 3 percent of 20
50%X=3/20+3/8
50%X=21/40
X=21/40÷50%
X=21/80

X / (x-120) = 12, how much is x equal to~
We have math （ ）Friday morning.
A.on B.in

x/(x－120)=12
x=12(x-120)
x=12x-12*120
11x=1440
x=1440\11
