Question

Rezolvati ecuatiile : 2x+1=4x-9 ; 1-3x= -2x -3 ; 4-2x = 1-x . Este urgent.

Answer 1

2x+1=4x-9

1+9=4x-2x

10=2x

x=5

1-3x=-2x-3

1+3=3x-2x

x=4

4-2x=1-x

4-1=2x-x

x=3

Answer 2

2x+1=4x-9; 2x-4x= -9-1; 2x= -10, x=-10:-2,x=5. ; 1-3x= -2x-3, -3x+2x=-3-1, -x=-4, 4-2x=1-x, -2x+x=1-4, -x=1-4,-x=-3,
