Question

URGENTE! me ajudem passo a passo pfv!!!

\( °_° )/ \[ *_* ]/

e)13+4(2x-1)=5(x+2)
f)4(x+5)+3(x+5)=21
g)2(x+5)-3(5-x)=10
h)8(x-1)=8-4(2x-3)​

Answer 1

Resposta:

e)13+4(2x-1)=5(x+2)

13+8x-4=5x+10

8x-5x=10-13+4

3x=1

x= 1/3

f)4(x+5)+3(x+5)=21

4x+20+3x+15=21

4x+3x=21-20-15

7x=-14

x=-14/7

x= -2

g)2(x+5)-3(5-x)=10

2x+10-15+3x=10

2x+3x=10-10+15

5x=15

x=15/5

x= 3

h)8(x-1)=8-4(2x-3)

8x-8=8-8x+12

8x+8x=8+12-8

16x=12

x=12/16 : 2

x=6/8 : 2

x= 3/4
