Question

1-resolva as equações de primeiro grau:


A)x+11=23

B)2x+14=30

C)9x+6=7x+4

D)53+10x-1=105-128

E)32-3x+18=25-4x+34

F)5+2x+43=15+5x-3+24

URGENTEEEEE

Answer 1

A) x+11 = 23

x = 23-11

x = 12

B) 2x+14 = 30

2x = 30-14

2x = 16

x = 16/2

x = 8

C) 9x +6 = 7x+4

9x-7x = 4-6

2x = -2

x = -2/2

x = -1

D) 53+10x-1 = 105-128

10x = 105-128-53+1

10x = 106-181

10x = -75

x = -75/10

x = -7,5

E) 32-3x +18 = 25-4x+34

-3x+4x = 25+34-32-18

x = 59-50

x = 9

F) 5+2x+43 = 15+5x-3+24

2x-5x = 15+24-43-5

-3x = 39-48

-3x = -9

3x = 9

x = 9/3

x = 3
