AJUDA URGENTEEE PRECISO DO RESULTADO E CONTA!!!!!

A 5x+7=4x+10
B 4x-10=2x+2
C 4x-7=8x-2
D 2x+1=4x-7
E 9x+9+3x=15
F 16x-1=12x+3
G 3x-2=4x9

Answer 1

A)5x+7=4x+10
5x-4x=10-7
x=3

B)4x-10=2x+2
4x-2x=2+10
2x=12
x=12/2
x=6

C) 4x-7=8x-2
4X-8X=7-2
-4X=5 
X=5/-4
X=-1.25

D ) 2x+1=4x-7
2X-4X=-7-1
-2X=-8
X=-8/-2
X=4

e)9x+9+3x=15
12x=15-9
12x=6
x=6/12
x=0.5

F)16x-1=12x+3
16x-12x=3+1
4x=4
x=4/4
x=1

G)3x-2=4x9 esse 4x9 não entendi deve ser 4x+9 
3x-4x=9+2
-1x=11
x=11/-1
x=-11

Answer 2

A 5x+7=4x+10 ==> 5x=4x = +10-7 ==> x = 3

B 4x-10=2x+2 ==> 4x-2x = +2 + 10 ==> 2x = 12 ==> x = 6

C 4x-7=8x-2 ==> 4x-8x = -2 + 7 ==> - 4x = 5 ==> x = - 5/4

D 2x+1=4x-7 ==> 2x-4x = -7-1 ==> -2x = - 8 ==> x = -8/-2 ==> x = 4 

E 9x+9+3x=15 ==> 12x = 15-9 ==> 12x = 6 ==> x = 6/12

F 16x-1=12x+3 ==> 16x-12x = 3+1 ==> 4x = 4 ==> x = 1

G 3x-2=4x + 9 ==> 4x - 3x = - 2 - 9 ==> x = - 11

ou

G 3x-2=4x - 9 ==> 4x - 3x = - 2 + 9 ==> x =  7
