G)2 (x +5)-4(5-x)=10


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


I)3(X-2)=4(-x+3)​

Answer 1

Explicação passo-a-passo:

G)

2(x+5) —4(5—x) = 10

2x + 10 — 20 + 4x = 10

2x + 4x = 10 + 10

6x = 20

x = 20/6

x = 10/3

h)

8 ( x — 1) = 8 — 4(2x — 3)

8x — 8 = 8 —8x + 12

8x + 8x = 20 + 8

16x = 28

x = 28/16

x = 7/4

i )

3(x — 2) = 4(—x + 3)

3x —6 = —4x + 12

3x + 4x = 12+6

7x = 18

x = 18/7

Espero ter ajudado bastante! )

Answer 2

Resposta:

A)2(x+5)-4(5-x)=10

2x+10-20+4x=10

6x-20=0

x= 20

6

x= 10

3

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

8x-8=-8x+12

8x+8x=12+8

16x=20

x=20

16

x= 7

4

C)3(x-2)=4(-x+3)=

3x-6=-4x+12

3x+4x=12+6

7x=18

x= 18
