Question

Resolva as equações.
2x+7x-10=4x+3-2x
2(3-x) = -4(x-1)
2-x/8 + x/3 = x+1/4
2x-3/8=2-x/4+1/6

Answer 1

2x+7x-4x+2x=10+3
7x=13
13/7

6-2x= -4x+4
-2x+4x=-6+4
2x=-2

6-3x/24+8x/24=6x+6/24
6-3x+8x=6x+6
-3x+8x-6x=-6+6
-1x=0
x=0/-1

6x-9/24=12-6x/24+4/24
6x-9=12-6x+4
6x+6x=12+9+4
12x=25
x=25/12
