Resolva as equações, sendo U =Q
Por favor e pra hojeeeeeeeeeeeeeéeeeee
Me ajudemmmmmmmm

Answer 1

B-
5(2x-1)=2(x+4)
10x-5=2x+8
10x-2x=8+4
8x=12
x=12/8
x=3/2 (Simplificado)
C-
10-2(x+3)=8+3(2x+5)
10-2x+6=8+6x+15
-2x-6x=8+15-6-10
-8x=7.(-1)
8x=-7
x=8/-7
D-
x-2(x-1)=4-3(x-2)
x-2x+2=4-3x+6
x-2x+3x=4+6-2
2x=6
x=6/2
x=3
E-
2x-3(4-x)=5+4(2x-1)
2x-12+3x=5+6x-4
2x+3x-6x=5-4+12
-x=13.(-1)
x=-13
