Question

RESOLVA AS EQUAÇOES
5 [ 1 - X ] - 2 X + = - 3 [ 2 + X ]
2 X + [ 3 - X ] = 5 - [ 3 X - 1 ]
3[ 4 + x ] - 2 = 2 [ 3 x - 1 ]
3 [ 2 x- 1 ] - 2 [ x - 2 ] = - 4 [ x + 3 ]

Answer 1

5(1-x) -2x = -3(2+x)
5 - 5x -2x = -6 - 3x
5x-2x +3x = -6 +5
8x-2x = -1
6x= -1
x= -1/6

2x + (3-x) = 5 - (3x-1)
2x + 3x = 5 - 3x -1
5x  -3x = 5 -1
7x = 4
x= 7/4

3(4+x) - 2 = 2 (3x-1)
12 + 3x - 2 = 6x - 2
3x +10 = 6x - 2
3x-6x= -2 -10
3x= -12
x= -12/3
x= -4

3(2x-1) - 2(x-2) = -4(x+3)
6x - 3 - 2x -4 = -4x -12
4x - 5 = -4x - 12
4x +4x = -12 +5
8x= -7
x= 7/8
