Question

1) 3x/4 +5=2x/3+2

2)2.(3x-5)/2=x/3

3)4x-3/2=2x+1/3

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

5)1-4x/5+6=2.(2x-5)/3+3

Por favor ajudem me!!!! eu preciso disso para amanhã

Answer 1

1)MMC(4,3)=12
3.3x+5.12= 2x.4+2.12
9x+60= 8x+24
9x-8x= 24-60
x= -36

2) 6x-10/2= x/3
MMC(2,3)=6
3.(6x-10)= 2.x
18x-30= 2x
18x-2x=30
16x= 30
x= 30/16= 15/8

3)MMC(2,3)=6
3.(4x-3)=2.(2x+1)
12x-9= 4x+2
12x-4x= 9+2
8x= 11
x= 11/8

4)3-6x/2+3x= x-2/5
MMC(2,5)=10

5.(3-6x)+10.3x= 2.(x-2)
15-30x+30x= 2x-4
-2x= -4-15
-2x= -19
x= 19/2

5)1-4x/5+6=4x-10/3+3
MMC(5,3)=15
3.(1-4x)+15.6= 5.(4x-10)+15.3
3-12x+90= 20x-50+45
-12x-20x= -93-50+45
-32x= -143+45
-32x= -98
x= 98/32= 49/16
