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=5x105-128
E)32-3x+18=25-4x+34
F)5+x2+43=15+5x-3+24

URGENTEEEEEEEEEEEEEEE

Answer 1

A) x + 11 = 23 23 - 11= 12 x = 12

B) 30 - 14 = 16 ÷ 2 = 8 x = 8

Answer 2

a) x+11=23

x=23-11

x=12

b) 2x+14=30

2x=30-14

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=5x (não sei se sinal de + ou -)

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

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

7x=59-50

7x=9

x=9/7

f) 5+ x ao quadrado??
