4x+3=16·475/1000
4x+3=76/10
4x+3=7.6
4x=7.6-3
4x=4.6
x=1.15

Answer 2

(x+1):(4+3)/4=4/7
(x+1):7/4=4/7
x+1=4/7•7/4
x+1=1
X=1-1=0
(x+25/100+1/2):475/100=35/100+5/10:10
(x+1/4+1/2):19/4=7/20+1/20
(x+1/4+2/4):19/4=(7+1)/20
x:19/4+3/4:19/4=8/20
x4/19+3/4•4/19=4/10
x4/19+3/19=4/10 |•190
40x+30=76
40x=76-30
40x=46
x=46/40=23/20= 2,3:2=1,15.
