Question

punctele e) , f) si g) va rogggg

Answer 1

e) 4x-0.(3)=3+x
     4x-x-3+0.(3)
     3x=3.3
     x=1.1. ver; 4×1.1-0.(3)=3+1.1, 4.4-0.(3)=4.1, 4.1=4.1
f) 5x+0.(5)=3+2x
   5x-2x=3-0.(5)
   3x=2.5
   x=2.5÷3
   x=25/10×1/3
   x=5/2×1/3
   x=5/6,  ver; 5×5/6+0.(5)=3+2×5/6,  25/6+5/10=3+5/3, 25/6+1/2=/9+3/3, /25+3/6=14/3, 28/6=14/3, 14/3=14/3.
g) 2x²+1/8=125/1000+x²
    2x²+1/8=1/8+x²
    2x²=x²
     2x²-x²=0
     x²=0
    x=0, ver; 2×0²+1/8=0.125+0², 2×0+1/8=0.125+0, 0+1/8=0.125, 1/8=0.125, 0.125=0.125.............sp.aj.  bafta
