a)2x+4=x+7
b)5x+8-3x=16+24
c)2(x+1)=10

Answer 1

Resposta:

Explicação passo-a-passo:

A- 2x+4=X+7 B-5x+8-3x=16

2x+x=7-4 5x-3x=16-8

X=3 2x=8

X=8÷2=4

C-2 (x-1)=10

2x-2=10

2x=10+2

X=12÷2=6

Answer 2

Resposta:

A) 2x+4=x+7

2x-x=7-4

x=3

B)5x+8-3x=16+24

5x+3x=16+24-8

8x=32

x=32/8

x=4

C)2(x+1) =10

2x+2=10

2x=10-2

2x=8

x=8/2

x= 4
