Explicație pas cu pas:
4-(-3)×[-11x+7×(-13)]÷(-28)=10
4+3(-11x-91)÷(-28)=10
4-(-33x-273/28)=10 |×28
28×(4-(-33x-273/28)=28×10
28×4-28×(-33x-273/28)=280
112-(-33x-273)=280
112+33x+273=280
33x=280-112-273
33x=-105
x=-105/33 |÷3
x=-35/11
4(3x+2)+3(2x+3)-28=7(2x+5)+6
12x+8+6x+9-28=14x+35+6
12x+6x+8+9-28=14x+41
18x-11=14x+41
18x-14x=41-(-11)
4x=41+11
4x=52
x=13
2(x+3)+3(x-1)+23=4(x+5)+15
2x+6+3x-3+23=4x+20+15
2x+3x+6-3+23=4x+35
5x+26=4x+35
5x-4x=35-26
x=9
